Re: Lightcarbon LCR72 "aero racing gravel"

I get that you dont like the short reach, i would also want it a bit longer... buuuut i dont get why you would not like steeper seat tube angle? Usually for racing you ideally sit more forward above the crank for maximum power, and it also open up hips more in aero position. Especially with short chainstay you compensate weight more forward.
An easy fix is also setback seatposts, which probably will also be available.

When i did a bike fit a few weeks ago, i had to slam my saddle all the way forward with zero-setback post, and i still miss about 1cm to have it perfect.
This is with 73.5deg seat tube and 'Comfort position'. Of course saddles have different rail positions so another with rails a bit towards the rear one may be better.

I do like steep seat tube angle. I meant it is usually combined with longer reach, that's why I said it's a weird combination.

I have the same problem. If a seat tube is too slack I have to slam it forward and still might end up having too much setback. On my Yoeleo Altera I run a 5mm setback post flipped around for -5mm setback.

Re: New ICAN A54 AERO FRAME with 35 mm clearance with this "S5" seat tube style, real world STA is maybe about 1-2° steeper then geo chart would suggest, depending on size and seat height.
So I would say even thou STA looks slack compare to normal bikes in reality STA would be much steeper than standard.

I would say this ICAN, XMCS VRT and light carbon LCR020 will have STA much steaper that geo chart would suggest.

I just tried to put geo reference picture to Fusion 360 and tried to align it. This is real STA that came out compare to geo chart in size M.
If someone have experience with this please pitch in If Iam wrong about this, I have never own this kind of geo on a bike, Iam just coming from my basic geometry knowledge :).

So every other bike that has two geo chart seat tube lines and seat tube does not come directly from bb center will be like this, STA much steeper than geo chart. Just another thing to be aware of when choosing a bike :)
