Inevitable if you ride consecutive days in the rain, not a huge deal. Lube it, ride, lube again. Do not attempt to scrape it clean or degrease with a chain cleaner.

It might need to be replaced, there's no way to tell with those pictures. What determines chainwear isnt rust, but how much the chain has stretched. You need a chain wear checker to see if it's time to replace, a simple one pictured to the left.

Fresh rust on chain is usually purely cosmetic. It should suffice if you oiled the chain, rode some, cleaned the chain to take off gunk and lube it again.

Thanks a lot, will get some oil this afternoon and see how it works out.

I just re-read OP and took a closer look at the pic.

See that bit circled in red? That's called sharktoothing. When your chain catches onto that bit there's a good chance it'll skip right over it, causing a stutter and jerk to your pedaling.

Worse, that shit accelerates chainwear. I would get that cassette changed asap.

You clearly need a new cassette, chain and big chainring.

Chainring looks fine to me, but yeah cassette for sure and chain as well probably just to be safe.

Luckily Shimano 6 speed cassettes are like 10 bucks, and a good KMC 6-7 speed chain is like 8 bucks tops.

Wow, I never noticed that, but that sure doesn't look like it's supposed to have that shape. Is it realistic to change the parts myself? I mean, sure it depends on how retarded exactly I am, but is it considered a hard thing to do compared to, say, changing the tires/tube?

Again, thanks a lot, I would have fucked this up badly on my own.

>>989458
You need a few tools but it's easy. If you keep riding it be careful. Don't stand up to cat 6 some niggaz with a beastly powerful attack because the chain could easily slip and fuck your shit up if your weight is forward.

Chain is super easy and quick, uniglide cassette removal will require specialized bicycle tools(definitely won't find them in a run of the mill tool kit.)

What you're going to need is a chain whip, two of them to be exact. Off-brand chain whips cost about 5-10 bucks and work just as well as the name brand stuff, which cost 25ish. Check out a video of the process here:

If you don't want to buy the tools I highly suggest trying to find a local bicycle kitchen/co-op. They will 100% have any tool you could possibly need and can assist if you run into trouble.

You need to wash your small hands of cheetos dust before lubing your chain anon

Also here's a picture of sharktoothing of the chainrings(the cogs on the crank.) From what I could see yours looked fine, but spin the crank a bit and see if there are any teeth that look like this.

>replace the chain it's out of spec.
>grease the niples
>hub is probably out of Spec too
>as for the webeel wable, your main bearings are probably toast.
>looks like break line is reached its end of life
>rough ride? New seat coils or front shocks if equipped.

Mate for the sake of your time and money just get a new bike.

That is not a shark's tooh, you spastic retard. That is a shifing aid ( release ramp for upshifting to be exact ).

Shark teeth go a different direction and are uniform over the entire sprocket.

Don't listen to those retards. Your drivetrain is fine, it has plenty of life in it. What you see on the cassette are shifting aids, specian ebossments and ramps on the cogs to aid chain changing cogs.

Take a look at pic related. Sram force, even more aggresively cut to make shifting as fast as possible.

Your drivetrain is fine, it just needs cleaing/lubing.

low self worth all up in this thread. have a bit of confidence op, watch youtube videos or just read wordy explanations until you understand what youve been told to do then do it carefully and good luck

>>989458
just oil it - it's fine.

Anon, the most you'll ever have to do for that is replace chain, replace cassette, replace cables, tune your derailleurs, oil your bearings/headset (if necessary).

I've got a friction shift bike that won't shift the rear derailleur. And if I manually move the chain it just shifts down again.

You have no wire housing. Aquire housing.

>>990596
No housing. Also please consider routing the chain through the cage correctly.

Definitely a moron, probably a troll. Your parents are really, really disappointed in you, for fucks sake do something productive with your life.
