>>
>>1088993

It sounds like they put a fork on that is too long. Maybe a 27" fork for your 700c wheel or something. This can fuck up handling if it's severe. Otherwise it's just annoying

Do you have the original fork? Measure the axle-to-crown height and compare it to your new fork

Your bike shop sounds dumb as hell. Hopefully it was cheap.

>What do I do now?

the cheapest step at this point is hunting down a long-reach caliper brake with cable release. options: https://groups.google.com/forum/#!topic/650b/TAI6lKW-Azw

I can't figure out why your QR doesn't fit in the dropouts. Maybe as the bike shop if they have any laying around to try. You can get hex-bolt locking axles on ebay for about $15
>>
>>1088995
thanks
The QR fits in but no matter how much I tighten it down slides around when I wiggle it at the top.
I have 700c wheels. I just held the forks up to each other. From the end of the crown or whatever right above the brake to the center of the dropout, the new one is about an inch longer. I asked the guy at the shop if he was going to double check the sizing but he said "700c forks are all the same" or something like that. It didn't sound right to me because of course, the geometry of every bike is going to be different and the rake distance isn't going to be the same.
It's a 1984 raleigh super course. Can I find a reasonably similar steel fork? Kinda mad at that shop now desu. I brought it back once to explain the slipping problem and once I finally got through to the guy to show him what was wrong, when I picked it up it hadn't been fixed.
>>
>>1089000
>The QR fits in but no matter how much I tighten it down slides around when I wiggle it at the top.
Are there equal amounts of ganged axle sticking out from the lock nuts at both ends?
>>
>>1089011
Yeah I think so. At this point I'm just gonna cut my losses with them and try to find a new fork that I can use my old brakes with. I spent like $150 to have them do an accident checkover and to replace fork, brakes, new tire, etc.

Here is my dilemma new bike well over bydget generally love it but it has a few weak points.
The fork is kinda weak but not a priority. At least its super light.
The breaks however... they are crap shimano br-356 or what with resin pads.

I want to upgrade to slx ice tech rotors and breaks eventually because i love to rip down even tho its an xc bike.

The rotor blades are resin only but i think i want to try semi metalic pads. If the rotor gets chewed up i replace them to ice tech. Then i replace the brakes eventually too.

Is this a good plan or not so much?
>>
>>1089051
Oh and what i want is more snappy breaks i have to pull less hard and have more braking power but also more thermal endurance eventually.
>>
>>1089000
>Can I find a reasonably similar steel fork?

Probably. But you're going to need to hunt on eBay for a fork that has the same axle-to-crown length AND steerer length. The top of the streerer is threaded and needs to be relatively close to the same length.

The other minor challenge will be to remove the fork race and put it on your new fork. Can be frustrating the first few times you do it, especially if you don't have the tools you need for the job

Is there a bike co-op anywhere near you? They probably have the fork you need for cheap, and someone to help you with the job
>>
>>1089059

* Crown race

And as a side note, all 700c forks are not the same! 1" difference is significant. Your bike now has higher trail, which makes the handling less sporty at slow speeds, but can improve stability at high speeds. Some like more, but your bike is probably better with the correct fork length

Very sorry for your shitty bike shop experience. A lot of people here got into building their own bikes for this reason. It's usually more expensive than you expect. A bike co-op or a local friend with tools is a god-send
>>
I think something is wrong with my hydraulic brakes. It seems like I have no pressure for the front one and I had to adjust the the back ones lever so that I need to grip extremely hard but I still get no pressure. I can see some part moving where it's not supposed to but I don't know shit about brakes. Should I just take it to a shop?
>>
>>1089079
yeah probably take it in to a good shop. Those rotors are tricky to align right and brakes are not the thing you want to fail when you're riding.
>>
Do rim brake pads have to be burned in like disc brake pads? Or will they work at maximum efficiency immediately their first use?
>>
>>1089079
What do you mean by 'no pressure'? Is your lever bottoming out against the bar? Does your lever feel squishy? Are your pads worn down? Is the lever pull longer than it should be? If you are running hydraulics and you don't know much about brakes you should probably go to a LBS.
>>
>>1089039
Just ride. You'll get stronger, faster, and more comfortable. Stop being a faggot and GO FUCKING RIDE. Right now. As soon as you see this post. Turn off your computer and go ride. I don't give a fuck if it's 3am and you have to get up for work in 4 hours. Just GO AND FUCKING RIDE, faggot.

>>1089043
It's good as a short-term job because it gives you experience and knowledge that you can then use on your own bikes. Not a good long-term job because the pay is really low.
>tfw currently a LBS mechanic, been LBS mechanic off and on the last two years, not gonna do it too much longer probably but it's been good for a while for the knowledge/experience I've gained
>>
>>1089051
Those brakes don't exist, do you mean M365? They ain't too bad, fairly similar to a lot of other Shimanos without servo-wave, but they could be better.

Rotors won't make much difference at the same size, Ice Techs won't heat up as much on long braking periods but that's it and honestly you probably won't benefit from it. Larger discs will also heat up less as well as giving you greater leverage.

Organic resin pads actually have more initial bite than sintered metallic pads and are also quieter, metallic pads have the advantage of fading less at high temperatures, perform better when wet, and they last longer. You can also get other compounds that behave similar to organic but have kevlar reinforcement for heat resistance and longer life.

I would suggest that to get the results you're after you should get M675 brakes (best value for money from Shimano) and try them with the stock pads, if they wear down too quick look at kevlar pads unless you ride in the wet a lot or you're a big guy (bigger riders produce more heat from braking). Similarly you can look at larger rotors to reduce heat (floating rotors even more so).

It's also important to make sure you bed the brakes in properly which you can even try with your current ones to see if there's any improvement. Lightly sand the rotor and pads and clean them well with soapy water, get up to a decent speed and apply the brakes hard but don't come to a complete stop, repeat about 5 times or so.

>>1089079
As the previous replies have said, take it to a shop. It seems like something is definitely wrong but with your limited knowledge there's not much we can do to help.

>>1089084
They're good from the first use. Disc brakes coat the rotor with material from the pad and mate the surfaces, that's not the case with rubber pads on rims (if the pads are aligned properly, if they're wonky the braking will improve as they wear to contact the rim completely flat).
>>
>>1089092
i'm definitely not small lately between 230-260 lbs. why i said the brakes are crap because i used shimano m445 before and even those were way way better.
>>
>>1089116
m446 sorry posting from the phone can't look up shit because it's awkward as hell. so the m446 with 160mm disks performed better than the m365 with 180mm disk.

it's not that i can't stop with the bike it's the muddy feel to the lever and how hard i have to pull compared to the other one. feels like a whole different category and the m446 is entry level stuff.
>>
>>1089085
sounds like it got some air if hydraulic...
>>
okay next question:
what are the benefits of center lock vs 6 bolt?
would it be worth upgrading the hub to get center lock disks if i want new disks or not?
>>
>>1089128
they are acera hubs btw, i would eventually upgrade them to deore at least in the future. it's all about schedule really and how much i plan to wear down the parts before i replace them. sadly the compatibility issues muck this initial strategy up a bit.
>>
>>1089129
from what i found is the lifespan of acera hubs can go from 5-12 years even barring some damage if well maintained but some people have broken them in 100km. hubs are not particularly expensive but the work involved in changing them seems daunting.

Are tubeless tyres worth it?

My rear tyre valves keep splitting near the steam, I think the tubes are slipping and/or the valve opening is sharp or something

I ride a mountain bike
>>
Best 700x28 tires for mixed riding?
>>
>>1089116
>>1089118
I would say something is wrong with your current brakes then because the M365 and M446 are pretty much identical. Try the bedding in procedure that I mentioned, it could be that yours weren't done correctly or your pads and discs are contaminated (you may need to buy new pads).

>>1089128
Centre lock is a little bit lighter usually and it's quicker and less fiddly to install the rotor, the downside is you need a cassette lockring tool to do it. There's no difference in braking performance so no it's not worth switching to if you don't need to.

>>1089161
I haven't personally used tubeless as I don't have a compressor to seat the tyres, but for how little it costs and the huge benefits it brings I would say it's definitely worth it. It won't fix your issue though, check your rim first and get any sharp shit you find filed down.

>Are tubeless tyres worth it?
Yes, definitely. Especially if you're running such low pressures that you have slip. That's what tubeless excels at.
>>1089166
>don't have a compressor to seat the tyre
Airshot. Pic related. I have one. 10/10 Would buy again.
>It won't fix your issue though
Yes, it will. The valve isn't fixed to anything but the rim in a tubeless setup, so there is nothing tugging at it like there is with a slipping tube setup.
>>
Are titanium frames ever worth it?
>>
>>1089170
I could get a compressor for not much more, maybe even the same price if I look around. I'll do it at some point, probably soon.

If the guy has a sharp valve hole then it could very well fuck up a tubeless valve too by pulling on the valve when inflating the tyre. Sure it's less likely to happen and may not even happen at all, but the real issue that needs fixing is with the rim.

It could also be that he's just buying shitty quality tubes in which case he just needs to buy better ones if he wants to save some money compared to going tubeless.
>>
>>1089173
If you want it and can afford it. The problem is titanium has the same stiffness to weight ratio as steel. Some people think titanium frames are very light, but they're only ever lightish, and if they are they're also very noodly.
But there are tons of other, mostly emotional reasons than grams to want the Ti. And if you'd like to have it and can afford it, why not?
>>
>>1089173
After carbon fiber became affordable, not even close.
You only get one if you think titanium is cool. If you want to go fast you get carbon fiber.
>>
>>1089175
>>1089177
Thanks, this just keeps confirming what I already thought.

But discussions with titanium owners put me in doubt, guess I was right that they are throwing money away for placebo.

Not (as) portable. Much noisier. Needs big tank.
>If the guy has a sharp valve hole then it could very well fuck up a tubeless valve too by pulling on the valve when inflating the tyre.
Pic related. Also, no. Even if there is a bit of burr it 1/ can't possibly be enough to push cut a 90 degree bore edge through a tubeless valve plug, and 2/ even if it did superficially score the rubber it wouldn't matter, and 3/ if it cut the rubber clean through it'd hit the metal beneath rubber hood and the sealant would take care of any microscopic leaks. The urban legend shitty self-asploding tube boogey man is complete bullshit.
>>
>>1089166
>Try the bedding in procedure that I mentioned, it could be that yours weren't done correctly or your pads and discs are contaminated (you may need to buy new pads).
yeah i already did that, i cleaned them with window cleaner (which is mostly isopropyl alcohol) and rubbed the surface clean. what i found in difference is that the m446 has some servo valve thing the m365 lacks if i understand correctly could explain the different feel. i also thought about what if the break fluid has some air bubbles and it's somewhat compressible but it's a brand new bike these sets are sold as closed system by the manufacturer the ones who put them on the bike don't tinker with them just screw them on.
>There's no difference in braking performance so no it's not worth switching to if you don't need to.
nice, i just want to do it eventually but it's not a priority right now because i don't want to spend $300 on the bike at this moment.
i can get new new disks for $100 i'm gonna try the ice-tech disks and increase the rear disk to 180mm from 160mm. that alone should give me better thermal performance with the resin pads.

how can you check for fluid comprehensibility in a brake system? is there a procedure to remove air from them?
>>
>>1089190
The M446 doesn't have Servo-wave, the lever is identical to the M365 other than some slight cosmetic differences. The calipers are also almost identical, performance will be the same but the M365 is actually better as it looks like it can take a banjo fitting on the side.

Air bubbles could be the cause of the issue, even with a brand new system. Take it into a bike shop and they should be able to tell you if it needs doing by the lever feel and it shouldn't cost much to have it done (it's also fairly cheap and easy to do yourself if you wanted). You may be able to tell yourself, you should be able to feel when the pads contact the disc and then if there's air in the system they'll be significant lever travel after this point, probably ending with the lever close to the grip.

>>
>>1089192
i realized what was the problem but thanks, the feel is much better now with a little adjustment on the mounting. i released the mounting bolts pumped up the brakes and re-tightened, because the brakes were pushing the disk sideways. i also set something on the brake handle where the cable is attached and now i get to pull less hard and it's more snappy.

feels like my old bike almost, can't wait to try it out on the trails.

damnit... so simple.
>>
>>1089193
is 7nm good torque for shimano caliper mounting bolts? i get conflicting information when i googled. i tried to measure the torque before i unscrewed them first but that's not necessarily accurate if the bolts are set in. it was definitely more than 6nm to make them move and less than 9nm.
i found 6-8nm in a manual but also found 2-4 and 8-10 wtf
>>
>>1089199
You really don't need to be anal about torque numbers in most cases, the exceptions mostly being when dealing with carbon parts like seatposts and handlebars. Just do them up tight but not stupid tight.
>>
>>1089202
interesting the manual i got for the bike says i should use the minimum torque and assembly gel if possible to get the most durability out of the bike.
>>
>>1089285
You can use anti-seize compounds on the threads to minimise the chances of getting stuck bolts in the future if you want, I've personally never used it and never had an issue but that's just me.

Torque numbers are just a way for manufacturers to cover their arses and to stop idiots either not doing things up enough so parts come flying off or doing them up too tight and breaking them. If you're an idiot or have little mechanical experience then by all means use a torque wrench, it may even help you to get a feel for things so you won't need one as much in the future.
>>
>>1089293
this assembly gel is not simply anti seize its like sand it has these particles in it silica or ceramic very abrasive. it increases friction manyfold between surfaces. it also acts as a grease to separate metals preventing a bind.
>>
>>1089309
I know what you're talking about, it's commonly called friction paste. It's not really needed with metal components as you can tighten fittings enough to clamp them, it's generally used for carbon stuff so you don't need to tighten it as much. The only places it's really of any use is seatposts and stems (from both the handlebar and the steerer tube clamps), everywhere else the surface area is just too small to matter.
>>
How often should you change your front tire with your back tire?

Never. You shoild buy a new front tyre when the rear wears out, and move your old front tyre to the back. You should never install a worn tyre up front.

>>
>>1089346
Re-negotiation of the value of the Japanese Yen to the US Dollar, accomplished by the mid-1980s "Plaza Accord," had the side effect of steeply raising the price of Japanese-made goods overseas, which especially hit the bicycle industry. Net result was that most Japanese brands withdrew from the US market, and both Nichibei Fuji (bikes) and Suntour (components) began descents that ended in bankruptcy. Panasonic, Bridgestone, and Miyata still make bikes for the domestic market

I had to replace the cables on my bike and no matter what I do I can't get the front derailleur to work. I've looked at maybe a dozen videos on youtube, but I can't shift onto the larger chainring.
When I attach the cable it and shift, it only moves slightly, if at all. When I tighten the cable as much as I can with the barrel adjuster it moves a bit, but never far enough to actually get it on the chainring.

Any ideas on what's going wrong? I'd like to avoid the damage to my ego and wallet from taking it to a bike store to get fixed if possible.

I found a place where they'll powdercoat a frame and fork for like $15 bucks, the place isn't a bike-related business so there's no hipster tax, though I still understand this is way cheap, I'd expect to pay around $50 or so
No idea about sandblasting, I've always just used paint remover, steel wool, sandpaper and a lot of patience

Just get a longer metal cage with a longer bottle and bend the cage open a little bit. I think I've gotten bottles that big in.
>>
>>1089673
750ml bidons fit standard holders. The diametre and fit is the same. It's just taller. Avoid blastig:DD holders and go for the steel ones. They'll hold a heavy bottle much more securely. If you're in the EU I can recommend Rose's own holders. Very sturdy, very secure, reasonably cheap and have been tested for 750ml bottles on washboard gravel. By me.
>>
>>1089673
Larger bottles fit in the same cages as smaller bottles, notice that the notch that the cage goes into to secure the bottle is at the same height (closer to the top on shorter bottles).

You can get them down to 25 but chances are even 32/37 would be fine. What's more likely to limit you is frame and fork clearance.

No, don't get a larger size. Honestly it's best if you don't get that bike if there's no size for you. It might be a deal but if it's not a good size for you then there's no point buying it.

Sorry for posting a third time but shit nigga buy a bike already. Oh here's what I wanted to say:
When it comes to big purchases, companies are usually open to negotiation. For example, if delivery costs is the difference between buying it and not buying it, contacting them and saying this (over the phone helps since you're directly negotiating with a representative) has a good chance of helping. So long as the approach is kinda fair, like expecting free delivery on shit that's like $700.

I want to take cycling more seriously since I only have a shitty city bike right now, I know that road bikes are better for going vroom vroom on but I live in a place with a lot of trails and gravel roads that I enjoy cycling on.

Will I really be held back that much by getting a hybrid now and getting a road bike later or should I just buy a sporty mountain bike and use it as a commuter when it's piss poor weather and for trail riding? I'm looking at getting something like this

http://www.bikesale.com/scott-sub-cross-30-men-commuter-bike-2017.aspx

Or this, but a bit more expensive

It's easier to find used road bikes for cheap here than hybrids or mountain bikes so I'm thinking that I might as well pick up a road bike later and get a bike that can handle rougher roads and conditions first, someone on my local auctioning website is selling a Scott Speedster 50 for half of what they go for new but I'm broke right now anyways.
>>
>>1089782
Nah dude get a cyclocross. They've got speed and can handle rough ground and trails.
>>
>>1089783
I want to but even entry level cyclocross bikes are expensive
>>
>>1089784
If you're broke then you should save up for a real bike instead of wasting money on a headache.

Does anybody know of any "tier list" of the different Shimano gears and brakes? Or is more expensive always better?

More expensive usually means lighter.
Once you're above tiagra there's very little actual improvement.

tiagra is department store bike tier, 105 is "current mainstream" and anything above that is fred shit

not really, no.
I mean, if you PUT it on a department store bike it is going to shift like garbage because the people that assemble those things are literally payed to do the worst possible job.

But if you do a clean, tight build it will perform just fine.

I have a steel road bike with an Italian BB shell. So far I've been using an old style BB (separate spindle and cups, loose bearings), but every time I ride on the rain I have to overhaul the whole damn thing since water, crud, dirt and pretty much anything else gets in there and makes a mess. I haven't been able to find a sealed Italian BB on any of the bicycle stores and workshops in my town.
Recently I came across a guy selling a Campy Athena sealed Italian BB for like $35, says it's in great condition and was recently serviced.
Is it worth it paying this much for it?
Is it a fair price?
Will I need a proprietary tool for it?

Any thoughts on the BB itself?
>>
>>1089829
Tourney is Walmart tier

Claris is shitty bike shop tier

Sora is decent budget bike tier

Tiagra/sora blend is bikes direct tier

Tiagra is decent budget bike tier

105 is real bike tier.

Ultegra is pick and choose components for racing on a budget tier.

Dura-ace is im a dentist so no budget tier
>>
>>1089845
Marine grease is sold at auto parts store.

They don't actually use it on boats.

It's for packing wheel bearings and sometimes CV boots on fwd cars.

Go to AutoZone and ask for water resistant wheel grease it's like $25 a tin

But the tin lasts forever

It's hard to say, there aren't just "best bike models" for given prices. For your low budget your best bet is to get something used, and since prices vary wildly from country to country it's impossible to say for sure.
You could also get something from bikesdirect, but I can't vouch for their quality. A lot of people around here seem to be happy with their purchases from there though.

sure, I had a lot of tiagra bikes when I was growing up. but we aren't talking about dura ace vs tiagra, we're talking about what's the point of diminishing returns, which is 105
>>1089812
I'm not familiar with the current-generation tiagra but if it's the same fussy design that the 5700 105 had, you're better off with an older 9-speed groupset or just going for one of the vastly improved 11-speed groupsets. the 10-speeds were just an awkward step that didn't work very well, the Windows Vista of groupsets

It should loosen clockwise, but if you're still unsure you can always look up the bike model and see what kind of bottom bracket shell it has.
Also blast it with WD-40 and let it soak for a while, it's probable you're applying force in the right direction but it's just stuck in place.

It isnt. It's exactly the same as the 11spd but minus one gear step. It is incompatible with older 10spd groups.
'Hurr-durr 105 is the sweetspot' is an example of rote learning of bro engineering and mindless soundbites. Not insight.

What is the board consensus on aero bikes?
>>
>>1090102

Pointless except for time trials and ultra-distance triathlons where you are conceivably in contention for victory.

Mass start: You have ten dudes motor doping and using PEDs to draft. If you don't, what are you even doing there?
>>
>>1090106
Have you ridden one? They look pretty cool but I hear they're uncomfortable.
>>
Any recommendations for spd compatible road shoes, less than 300usd? Comfort over absolute stiffness.
>>
>>1090108

I think we may be talking about different things.

You are probably talking about pursuit bikes, like the one in this picture. That's quite a bit different from an "aero" bike.

A pursuit bike is intended for a very specific, short duration type of velodrome racing in which it is super important to be able to get as low as possible to draft efficiently and to avoid letting other riders draft you efficiently. People that ride them on the street are idiots.

An "aero" bike would generally be one designed for riding in events where drafting is either prohibited or impossible (because there is nobody else on the course).
>>
>>1090120
Dude I think when people refer to aero bikes these days it's about aero road bikes. Plenty of people use these as their standard road bike

Flatter tubes, probably more integration and potentially proprietary bullshit like brakes.

If you're buying a nice bike and don't spend all day climbing hills then it's certainly not a bad option.

How far will you be riding on road? You could always just get a mountain bike, it will be better on road than the cross bike will be off road (fully rigid with skinny tyres, shit geometry, and drop bars suck unless you're just riding on dirt paths, in which case a cheaper road will do the job nearly as well).

if you have to interact with non-cyclists just lose your expectations about what a normal interaction is

most of the time being in spandex is not a problem but any trivial confrontations that under normal circumstances would be shrugged off and forgotten can go nuclear before you even know what happened, simply because of your sexy sexy spandex. it depends on the person you're interacting with, educated folk are fine, but working class people get incredibly triggered

spd as in two-bolt mountain cleat, right?

Shoes are always going to be very personal preference, but I've been using the giro republic and they're not bad. The pontoons around the cleat are super close though, you might need to angle the cleat a particular way or use a shim to actually allow you to clip in. Not a clever design.

I don't think it would be the cables, perhaps if it was happening on the downshift it could be crud in the housing preventing the cable form moving freely and fighting the spring in the derailer but it shouldn't affect shifting in the other direction (except requiring more effort to shift). My best guess would be it's cause by excessive chain and/or cassette wear.
>>
I just got a bike recently but I THINK the front brake cable is a little too long. Would a longer than required cable/housing affect braking distance/stopping power?
>>
>>1090414
More cable means more friction and more housing compression (wasted power) but it's not going to be a significant amount. Shorten it if you can be bothered and are sure you won't shorten it too much, but don't worry about it if you don't want to do it.

I just tore apart my old steel bike and greased everything with bearings and now when I apply any pressure to the drops either left or right I hear a horrible creaking. Does this mean I put the fork back on too loose or too tight or could it be because I greased where the stem slides in?

Did you remember to greaser your rims? They're pretty much a big bearing.

I fell for the "I'm a big boy" meme, and got a bike that I was in the range of (for ex, I'm a 185, so got the large equivalent in that pic) I don't have full elbow extension in my right arm, so will always get a smaller bike than the manufacturers recommend from now on, its much easier to make a smaller bike fit a larger rider than the other way around

also get a handlebar with more back curve, and you can get a seat clamp that bends less backward.

where the /fuck/ do I find a 700c threaded unicrown cromoly stem? i know that isn't the standard anymore but they have to be somewhere. fuck.

reverb or an other drop seatpost worth the price for an xc bike? the truth is i enjoy the downhills a hell of a lot more than the climbs but the ideal seat position is obviously totally different for the two. i would like to ride a bit more technical trails too maybe sure the xc is not made for that specifically, but i guess that just limits my speed in the end.

i'm gonna replace the disks for ice tech sm-rt99 180mm ones and the break system probably for slx in the future. when the fork kicks the bucket in a few years i'm getting a reba thru-axle fork too. the drop seat is also part of the changes i'm planning.

that should pretty much max out what a hardtail can do and it still remains an okay xc bike.

>>
>>1090610
Don't bother with a Reverb, stupidly expensive for no benefit. Actually it's worse, it's less reliable and more of a pain to maintain. I can recommend the DNM ASP, cheap but decent. The remote is a bit crappy but does the job, but if you did want to change it there are plenty of replacement options (I've got an Easton Haven remote that I'm going to swap to).
>>
>>1090628
i would even be okay with a drop post with no remote just a lever to be honest. on our usual rides there are fucklong descents and climbs not much variation.

i don't want to fuck up my seatpost tho with constant changing and also don't want to waste time doing it so that's why i want a drop post.

sure remotes are convenient but i can't understand why the big brands don't make options for levers.
>>
>>1090633
KS make some lever posts but they're not any cheaper than ones with remotes. There are plenty of old models though if you're fine with going second hand. If you didn't want to take up handlebar space or can't be bothered running the cable the DNM post I mentioned can also be actuated by hand, a little fiddly to do whilst riding but easy enough if you stop. You could also just leave a short bit of bare cable hanging and tug on that.
>>
>>1090638
why is that lever and normal posts seem to go at lower drop length than stealth? they top out at 100mm.
>>
>>1090649
By stealth you mean those with internal cable routing, right? Those can drop far more than 100mm, 150mm isn't unusual and I think there are even some that go to 180-200mm now. That's because they're generally a higher end option and the higher end frames have internal routing.

itll b hard in the beginning, but if u keep at it it will feel like nothing.

>>1090412
does the chain and shit rly wear down after 400 miles? i always clean it and regrease etc
>>
>>1090661
I honestly have no idea how long a chain/cassette/chainrings should last, I've never worn one down myself as I end up replacing them for other reasons. Riding in adverse conditions will accelerate wear as will using the wrong type of lubrication (wet lube in dry conditions will attract grit, dry lube in wet conditions won't last as long). 400 miles does sound a lot less than I'd expect though, even with my short commutes that would mean I'd get through a chain in like 6 months and I've had rusty chains that I've never relubed last longer than that.
>>
>>1090454
>>1090473
It was coming from where the handlebar connects to the stem. I hadn't messed with the bolt at all there. It arbitrarily decided that the day I take everything apart it would creak on me. Grease fixed it.

I want to lower my stem. I am planing on puting a 10mm spacer above my stem. ..is this a bad idea, carbon forks needing the internal compression plug.

My question is...is 10mm to much above the stem?

>>1090652
they are about the same price tho. that's what i can't understand. price diff is minimal at a certain line.

Yeah, but their are less cheaper options for internal routing. Of course there are high end options with external routing, there were still high end frames before internal routing was common.

I just recently bought my first hardtail with a 2007 Rockshox Reba SL fork. I want to service it with a seal overhaul kit. How hard is this process?

I dont really have a question this is just the best place to talk about it
Im gonna build my first pair of wheels and I'm really excited about it. Sun ringle rhyno-lite rims, shimano 105 hubs.
>>
>>1090778
this reminds me of an other question.
let's say you have a rockshox tora which is no longer produced. let's say you want to change the coil to a extra soft one because the rider weights less than 60kg.
how would you go about finding a coil that can replace the current one?
it's a bike bought used we don't know the exact production date we don't even know the exact type or travel. i guess that should be the first to determine but how? also what coils could possibly be compatible with a tora?
>>
>>1090778
If you've got a service manual to hand, all the correct tools, and the time and patience it's not that hard.

>>1090797
If you're lucky the serial number on it will be able to date it but I have no idea which manufacturers do this or where you'd look. What I do is narrow down the general year based on the shape of the lowers and then get the specific year from the stickers (they tend to change every year), then to get the exact model I match up the features such as air/coil, travel, adjustments, etc.

Finding out how much travel you have is easy, just remove the top cap so the spring can slide out and then you can easily compress the fork, put a cable tie on the stanchion and use that to mark full compression and measure from that to the dust seal at full extension.

As for the spring, you don't need a specific replacement. As long as it's the right length and diameter it'll be fine. Forks with the same stanchion size will generally have the same diameter springs so that narrows it down a bit. Spring length is more difficult as it won't be the same for every fork of a certain travel so you want to ask the seller to measure it. Just make sure you don't get a spring fork a fork with less travel even if it is the right length as it may not compress enough.
>>
>>1090798
serial is a nice tip, after some search i found rock shox should have the year as the first two number of the serial on the back of the crown thx.

worst case we measure the travel as you said. altho wouldn't spacers change this with a coil spring? it would definitely work for air springs but coil compresses differently.

we already know it's not an air fork.
>>
>>1090801
I know it's not air, just saying that's one of the things I use to identify a fork.

>worst case we measure the travel as you said. altho wouldn't spacers change this with a coil spring?
Spacers can do two things, either preload the spring to set the sag for forks without external adjusters or they can reduce the travel. Preload spacers won't effect the measurement but travel spacers will. Travel spacers don't limit how much the fork compresses but rather prevent it from going to full extension.

I recently converted my old road bike into a flat-bar bike. Nothing changed with the shifting because down tube, but I needed new levers and cables. I bought some levers and cables, except that the cables came in the housing. This would be fine, except that the cable is some sort of shitty universal one with both flat and drop bar cable ends. My bike has an area under the top tube where the wire is exposed. How the fuck am I supposed to cut the cable housing with the wire inside? And I can't remove the cable from the housing because that would mean cutting one of the ends off, which leaves a frayed end that would be impossible to put back in the housing. I'm actually stuck. The only solutions I can remotely see are getting some specialized tool to cut the wire cleanly so I can remove it from its housing, or just getting cucked and buying another set of cables and housing. Any suggestions would be greatly appreciated.
>>

If don't go full ape on it it's fairly easy to get a clean cut with a pair of wire cutters, the strands will separate but you just twist them back together.

A good quality pair of pliers will cut through the cable no problem. The universal cable is intended to be cut at the end you're not using. Provided you get a clean cut the cable will stay together, it'll be easy to thread it into the housing.

As for cutting housing, the same pliers will do. Almost any tool you use will leave the housing in a mess, you need to clean up the cut by using a file, wet and dry paper, or a grinding wheel. The end of the cable should be square and flat. Stick a toothpick in the plastic cable sheet and wiggle it around to make sure the cable won't snag as it exits the housing.

Remember to use ferrules and cable end crimps.

Uni student here, just lost my bike while on a job because I'm a fucking idiot and didn't lock my bike.

I've got around a budget of £400 and I'm looking for a decent hybrid or road bike that can handle gravel road.

My old bike was pic related, I really enjoyed the brakes being a toggle as opposed to the spinning handle one. Here are some candidates that I'm looking at, can you guys shed some light on these?

The distance shouldn't be a problem at all, especially after the first several rides. If you're ONLY commuting on it, not long-distance recreational riding, a hybrid bike might suit you better than a full-on road bike. What's your budget?
>>
>>1090860
> solely for transportation
Don't get some meme-level road bike with ultra-narrow tyres and no mudguards or pannier rack, because that's impractical.

>on nice bike paths
Don't get a serious offroading mountain bike with knobbly tyres and full suspension, because that's really inefficient for normal riding on nice cycle paths.

But in general, what >>1090861 says is pretty true.
>>
Just started cycling and the bike I got came with a seatpost that's too short for me, so I'm getting a new one. Thinking of getting one with suspension because some of the "bike lanes" around here are literally rock paved roads.

>>1091415
>Large bike, short post.

Not really a thing.

It sounds like you are perhaps looking for a road/hybrid riding position from a compact MTB style frame?

I'm guessing you have a sloping top tube. If you don't, the bike is entirely the wrong size for you.

If you do, though, part of what you need to do is just get stronger. A lot of time spent riding on a MTB happens while riding out of the saddle in "attack position". You should be able to pedal for extended periods with a relaxed body position while standing on a frame like that. If you can't, your fitness is the main thing that needs to improve.

This is an odd question but... anyone have a better way of carrying a suit jacket on a bike when commuting? My current technique is to put the jacket in a garment bag on a hanger, put the hanger around the seatpost, then drape the bag over my rack and panniers, the whole thing gets held in place with a bungee cord. See picture for the general idea (bag is empty in this case, and normally the bungee cord goes around the outside of the panniers).
>>
>>1091742
no, i don't, but if I ever have to transport a suit jacket, I'll probably use your technique.
>>
>>1091742

Why don't you just have your dry cleaner deliver your jackets to your office instead of your home?
>>
>>1091742
Put in bag, fold in half, put bag in solid container (like a milk crate), secure container to rack, cover container
>>
>>1091742
I do the same thing that I do when I fly,.. jacket turned inside out, trousers folded inside the jacket

the entire thing goes inside a pannier. and the shoes go in the other pannier along with comb, deodorant, socks, underwear, belt, and so on. as long as you're not wearing like super 150s or something retarded like that, it's going to be fine

the bigger problem is the shirt and tie. broadcloth is out of the question, poplins are not so great either. no print ties, no ancient madder, no reppe. you need slightly textured everything and simple solid colors to disguise the wrinkles or at least make them forgiveable. for me it is royal oxford for the shirt and a garza fina grenadine tie, the slight roughness of both makes any wrinkling look possibly intentional

>>1091769

>why carry anything on a bike when you can use a cage, hurr bikes are for fags DAE XD

I've never, ever bought a quality tool and later regretted it. Even the kinda niche ones it's like, "damn I'm really glad I have this!". A good torque wrench is definitely not niche.

Except torsion bar torque wrenches aren't iffy in the slightest and much more accurate within their range than a clicky spring loaded thingamabob that hasn't been calibrated in a year or so.

There is absolutely nothing wrong with the Canyon torque wrench. Except that it is ranged for finishing kit rather than 40 N/m cassette lockrings, but we've established that already.

How ok is it to use a 29er fork on a 27.5 frame and wheels?

I intend to replace the sus fork on my hardtail with a rigid one, and here I have much better options if I pick a 29'' one.

My current frame has a 71/73 head/seat angles with a 100mm fork. Will putting a 29 suspension corrected fork really fuck with my geometry? I know its probly gonna slack up a bit but it's not gonna make my bike handle like an 18 wheeler truck. Or will it?
>>
What makes normies unable to drive on a Friday night?

Everyone just seems to drive faster and pass closer on a Friday.
>>
>>1092098
It will probably change the geometry, but whether it will be better or worse is hard to say. If it's a longer fork then you'll slacken the head angle (generally good to a certain extent), slacken the seat angle (bad), raise the bottom bracket (bad), increase the wheelbase (usually good), increase the trail (good or bad depending on who you ask, may not change much or at all depending on the offset of the forks). Depending on what and how you ride you may find some of those trade offs to be worth it, or the difference may be small enough that it just doesn't matter.

Also you can go the other way, a suspension corrected 26" fork will have enough room for 27.5 but be shorter.
>>
>>1092098
>I intend to replace the sus fork on my hardtail with a rigid one, and here I have much better options if I pick a 29'' one.
The radius difference between 29" and 27.5" is only 19 mm. That's about the error margin for suspension compensation anyway. Or the difference between the extra sag of a plush fork setup and low tyre pressure, or a pumped up or locked out fork and hard-pack tyre pressure. No one has ever claimed that to turn the bike into an oil tanker.

So in the grand scheme of things it won't even matter for a rigid fork. Choose the 29" forks if they're cheaper/better/more available.

>>
>>1092137
your geometry changes all the time on a suspension fork. a 100mm fork with a 20mm slag means it still has 80mm to accommodate a 29" wheel. so you would need to buy an 80mm suspension corrected rigid fork for the same geometry. if you buy a 50mm corrected it should be the same angle with a 27.5" wheel.
>>
>>1092140
I had a 120 mm fork on a 100mm frame and it fucked a whole lot of things up including the frame headtube welds while having slow steering that overshot corners.
>>
>>1089741
besides who needs disk brakes on a road bike?
>>
>>1092143
Suspension corrected just means long, you can't get forks corrected for a specific amount because even at the same travel amount fork length can vary quite a bit across models and manufacturers.

A 29" suspension corrected fork will most likely be longer than a 27.5" fork of around 100mm travel even at full extension (so not including sag) so yeah it will affect the geometry in all the ways I mentioned.
>>
>>1089782
i went from a road bike to a Scott sportster x20 sub hybrid and im never going back to road bikes for riding around town, the seatpost suspension is great for shit roads and the gear setup makes is great for climbs, The only bad thing about hybrids is you are never gonna be hitting the heavy gears unless youre riding downhill with the wind on your back because wheels are too grippy and not thin enough for speeding

What do you call the gold/copper/chrome piece on this brake lever? I need to replace one of mine because it is all bent up but I can't find the right word to describe it or know where I could get a replacement.

tl;dr: chainline fucked, ok to change BB to fix it?

I'm fixing a BMX, the chainline is way off and the chain keeps dropping. Just eyeballing it the chainring is much further out than the rear cog. I took out the BB and measured it to 123mm. I was thinking that I'd get a 113mm Shimano UN26 to bring it closer.

Does this sound like a reasonable fix or should I do something else instead?
>>
>>1092264
I'd just get new levers, you are unlikely to find that small part.

If it's some period correct vintage build.. good luck.

>>1092327
Ride more, it gets better as you get used to sitting in the saddle. Also try adjusting your position on the bike. In my experience a too low saddle height hurts your ass. Also, a bit controversial, but if your handlebars are too high it might also be worse on your ass.

Need this answered as fast as possible.

What's better for a front hub? loose or caged bearings? I wanna go loose since this is the 3rd cage I've cracked in a year.

If loose how many balls do I put on each side and should I use the same ball size as the caged bearings that I've used so far?

what's the deal with rear suspension?

Whenever I've ridden one I've found it just robs so much power from your pedal stroke.
>>
>>1092416
A decent shock and a decent suspension design (the actual frame) can pedal quite well. Of course you're always going to lose some energy and you have the extra weight to deal with, but depending on what you're riding the increased traction and bump absorption can be worth the trade off.
>>

Cheap ones suck ass, some of the expensive ones aren't annoying if you pedal smoothly... but those bikes cost over 2000€/$

>>1092471
A decent shock on a cheap and simple frame will usually pedal better than an expensive frame with a not so good shock, the exception maybe being frames specifically designed to pedal well with a lot of anti-squat. You don't need to spend anywhere near that much to have a full susser that pedals well

I'd personally replace the tyres and saddle, if you don't mind spending more than what you paid for the whole bike.
>>

Ill definitely replace the saddle yeah, tires are actually fairly new i think, and im clueless as to how to pick appropiate tires so i might hold on that for now
>>
>>1092522
Remove the accessories that you don't need. Find the right tire pressure for you, the tires should give a bit when riding over rough stuff so they don't rattle you and the bike to bits, but too low and it makes the bike slower and more likely to pinch the tube.

got some new disks i got impatient and put them in realized after they are "narrow type" disks while i have the standard shimano b01s pads in the br365 brakes. now the pads are obviously wider than they should be by a few millimeters what will this cause? is there a chance of my pads biting into the arms and causing a potentially fatal lockup?

if the brake pad wears out faster i don't give a fuck, i will replace the brakes to slx eventually, if the disk wear out faster that's a problem but maybe i can deal with it. if there is a chance of a bad lockup tho i would like to know about it.
>>
>>1092748
> they are "narrow type" disks
First time I've ever heard that term. Are you trying to say they have a narrow braking track? That's not really a type, just a property of the discs.

>i have the standard shimano b01s pads in the br365 brakes. now the pads are obviously wider than they should be by a few millimeters
Those are the correct pads for those calipers, they shouldn't be any larger than they're supposed to be.

> is there a chance of my pads biting into the arms and causing a potentially fatal lockup?
It should be quite obvious if there's contact between the pads and rotor carrier. I doubt there will be as the rotor will top out in the caliper before that happens (and you'd need to be using the wrong sized mounting adapter).

If that photo is the rotors you've actually got then a more likely issues would be the pads hitting the aluminium cooling fins. If that does happen you'll want to space the caliper out slightly with some washers between it and the mounting adapter.
>>
>>1092749
the g01a pad is the one i should be using with this rotor rather than the b01s, it is a few mm less tall and few mm more wide than the b01s.
it belongs to the higher end brakes.

they don't hit the alu fans thankfully, what i'm afraid of is the following:
>lower 1mm of the break pads has way less contact surface than the upper part, which will result in less wear, so the brake pads remain thicker there, and they chew into the section above the arms attachment point badly resulting in wear on the steel plating more significantly than the part that should be used for braking normally, and will also decrease the efficiency of braking. and worst case get stuck and lock up the wheel or bend the disk.

and of course if i use spacers to adjust the contact area on the bottom this will happen on the top.
>>
>>1092751
You must not have a 365 caliper then because that uses the smaller B01s pad, as you say the G01a pad is for higher end brakes (my old XTs had them) and the M365 is a low end system.

>lower 1mm of the break pads has way less contact surface than the upper part, which will result in less wear, so the brake pads remain thicker there
How so? If the caliper was sitting too high on the disc then it could end up thicker at the top (not a huge issue) but I don't see how what you're saying could happen.

>and they chew into the section above the arms attachment point badly resulting in wear on the steel plating more significantly than the part that should be used for braking normally
Let's pretend the cooling fins weren't there and the pads where sitting too low. The pads are a relatively soft material compared to the disc, the part just above where the arms attach would wear down the pads just like the braking surface does and the pads would wear quite evenly. There's no way it would end up causing significant wear to the rotor.

>>1092752
As I said above, that's not really a huge issue. You lose some braking performance as there's less surface area applying force but it's not dangerous. However I'm pretty sure the braking track on those Shimano discs are going to be deep enough for any Shimano pads, it'd be retarded of them to make it otherwise.
>>
>>1092754
>However I'm pretty sure the braking track on those Shimano discs are going to be deep enough for any Shimano pads, it'd be retarded of them to make it otherwise.
sadly it appears so. i have overhang either up or down, up will cause uneven wear on the pad which i have to periodically correct or risk brake failure as the pads worn down, if i don't use spacers i put the risk of excessive wear on the disks.

i see your point about resin pads being soft compared to the steel, but i can see on my old pads where they bit into them how much they worn away.
>>
>>1092755
>up will cause uneven wear on the pad which i have to periodically correct or risk brake failure as the pads worn down
It's not going to cause a failure, just some lost braking performance and a bit faster pad wear (as it's spread over less area).

>if i don't use spacers i put the risk of excessive wear on the disks
On a regular disc it would've be an issue, but on those Ice Techs you risk damaging the aluminium fins.

>but i can see on my old pads where they bit into them how much they worn away.
If there was significant wear on your old discs they were either really old, your pads were contaminated with grit, or you ran the pads down to the backing. Just think about it, if a tiny lip of pad material was enough to wear through the arms of the rotor then the braking surface would last very long at all. In fact a lip won't even form as it'll be worn away by the arms.
>>
>>1092754
i measure the difference in the tracks on the old brakes the contact area appears to be 16mm, the ones on the new rotor seems to be only 15mm.
so there will be 1mm overhang either direction i can decide put in 1mm spacer and it's safe for rotor but less braking performance and regular sanding the pads. not put in and the wear on the rotor might be more sever than it should be.

i don't know which one to pick until i get my new brakes. i wanted them for christmas or something. unless i was really displeased with the braking performance in which case right next month.
>>
>>1092757
>It's not going to cause a failure
i mean if the unworn part of the pads touch and it causes sever brake fade. i know it shouldn't cause serious issues unless you know the front axle moves because of a jump and the top of the disk bites right into the rims.
>but on those Ice Techs you risk damaging the aluminium fins.
the aluminium fins look further down by 2mm from the overhanging pad they look quiet safe.
>In fact a lip won't even form as it'll be worn away by the arms.
i would really like that, i guess in a few weeks it shouldn't develop any serious issues aside from aesthetics.
>>
>>1092760
>i mean if the unworn part of the pads touch
You'll probably be replacing your pads before that happens (especially if you're getting new brakes soon), but even if it didn't happen the pads would just pivot and begin wearing at an angle.

>the aluminium fins look further down by 2mm from the overhanging pad they look quiet safe.
I'm not talking about just the fins specifically but the entire aluminium part. I've never seen Ice Tech rotors in person, is that aluminium part not level with the steel braking surface? If it's not then I guess having the pads too low is okay, as long as they clear the actual fins.
>>
>>1092762
>I'm not talking about just the fins specifically but the entire aluminium part. I've never seen Ice Tech rotors in person, is that aluminium part not level with the steel braking surface?
no the steel plating is over it i think it is exactly level to the aluminium core.

Is cyclocross a meme?

It just seems to be based around using a road bike on terrain you're not supposed to use it on. Where a mountainbike or hybrid would be faster
>>
>>1093234
You've pretty much nailed it. It's like a three-legged race, purposely handicapping yourself and seeing who's best at doing something the wrong way.
>>
>>1093234
actually if mtb would be faster people would ride mtb on cyclocross races don't you think? there is nothing stopping you from riding a full sus mtb in a cx race.

the thing is on certain specific terrain like i think grass they are the fastest partly because of the no suspension. if you mix roads in he race the mtb again will suck ass, but there will be parts of the course where a roadbike would simply not be able to pass which an mtb would take easily but then again at other parts the cx will leave you in the dirt.
>>
>>1093325
People do ride CX races on mountain bikes and have won. The thing is CX courses are tamed down so that you don't need full suspension (front may help, but it better be light), the areas that you have to dismount for put an emphasis on low weight, and the restrictions on bar and tyre width (500mm and 33mm respectively) make it so you won't gain as much on a flat bar bike with clearance for larger tyres.
>>
>>1093349
it would really depend on the ratio of woods and dirt vs asphalt and grass for the course if mtb is a valid option. if it's balanced it's all 50/50.
>>
Is there a good cheap bike computer? I don't want anything fancy, no phone apps either. Just want a little digital readout of distance traveled over time and speed, basic stuff.

>there is nothing stopping you from riding a full sus mtb in a cx race.
Depends where you live, I don't think USA CX follows the UCI rules but in europe you'd be bound by them.

I think the biggest gain rather than suspension would be tyres <40mm wide for a lot of the shit they have to ride over.
>>
>>1093487
to my knowledge all of them are crap.
i'm trying to push my company into developing an entire new line of products. or create a startup with crowdfunding. it's not the computers that are the biggest problem it's the complete system and how it works that's so last century.
>>
it's late at night here, but my bike which i wouldn't mind riding again has brakes that are completely fucked, they barely do anything and just make a screeching sound, is it just the pads or something else maybe?

the bike is 20 years old and is in need of some love
>>
>>1093835
if you haven't replaced the pads in 20 years, then the compound may have gotten old and stiff, or they might be worn-down too far, or both. replacements are stupid cheap so go for it. the /n/ recommendation is Kool Stop salmon pads in the same shape as the old ones.

screeching could also be the angle the pad is hitting. search sheldon/youtube about "toeing in brakepads."

never a bad idea to clean the grime off the rim contact area, you'd be surprised how filthy even clean-looking ones are.

also, deadthread.
