Man, screw the UCI. I want cool as shit aero frames.

OP is a downtube.

How comfortable is it to have no seat tube though

Y-foyle fagz are the recombant fagz of fred biking. Like the intra urban foamers of train fags. Like, you're an electro-chemical engineer and everybody else is just mechanical fags. Fags.

If it has a separate seat post it still has a seat tube. To be considered seat tube less in any way it would have to have an integrated seat post, or one of those seat mast things that attaches any way other than sliding inside another tube.

There's also a more common frame that has a carbon fibre boom that's designed to flex as a form of comfort suspension, can't remember the name though.

That's the one. Cheers, it was really bugging me that I couldn't find it.

Oh shit! Beam bike thread?

While they are not as cool looking as some of the carbon Ys (Zipp, etc), I've always liked the Titanflex frames for their highly adjustable top-tube length.

I just noticed the crank arms.

What the fuck did I post?

>>956459
I don't recall the name, but those are crank arms with built in freewheel ratcheting mechanisms that move independently, the theory is that they're supposed to be good for training riders to put out effort throughout the entire swing of the pedal stroke, and equal power from both legs.

Weird.
I guess I'd try it.

Fuck off downtube

Whilst it's a nice idea it's not really adjusting the top tube length (well, it technically is but) rather it's just an alternative to moving the saddle forwards or backwards on the rails (with a bit more range of adjustment).

To change the top tube length you'd want to move the headtube in relation to the bottom bracket and keep the seat still (relative to the bb as well). You'd need some sort of break just behind the headtube with either a sliding mechanism or removable spacer pieces.

>>956547
You're assuming it's a road bike.

TT bikes vary quite a bit in seat tube angle, so on a TT bike, TT length has just as much to do with effective STA.

>>956441
Where are the shifters?

>>956552
Sure, but that bike essentially has an adjustable seat tube angle. Yes that does change the top tube length but that's just a consequence. It's like saying that by changing tyre size you're changing the bottom bracket height, whilst technically true it's not the primary objective nor the best way to achieve it.

>>956553
It only needs one so it's probably on the left side hidden from view, either a downtube shifter or bar end. Either that or it's just not cabled up, the image is too small to tell for certain where the cable would come from the derailer (it looks like it may exit from the rear and loop round).

>>956554
But it's a TT bike.

>>956555
With an (essentially) adjustable seat tube angle. A by product is the top tube length also changes. What kind of bike it is doesn't make any difference.

Titanflex poster here.
You are of course correct.

But if I had said, "I like the Titanflex design for it's highly adjustable seat-tube angle!" some other cheeky fuck would have chimed in about that phrasing as well, as it is a bike with "no seat tube".

What a beauty. I'd prefer other wheels though. These look too dark to fit the bikes colourway
