The problem is that the smaller frames don't really get that much smaller with most manufacturers, both because they don't know how to handle issues like toe overlap and because they don't really understand the correlation between effective toptube length and seattube angle (as unbelievable as it sounds that bike companies sometimes don't understand bike geometry, it's really true).
    I agree with most of Cervelo's philosophy (because I can fit just fine on men's frames, and I felt horrible on WSD frames), BUT I just wanted to say that I find it extremely ironic that the worst case of toe overlap I've ever seen is with my friend who rides a tiny Cervelo. Just sayin'...

    If all bike manufacturers thought like Cervelo, my husband and myself would probably be stuck buying custom....

    I ride a 48cm Cervelo P2C as my TT/Tri bike. With the proper length crankarms and clipless pedals....zero toe overlap. The 48cm Cervelo RS...zero toe overlap. The 48cm R3-SL...zero toe overlap. Those three bikes are MARVELOUSLY designed small frames.

    What frame is your friend riding? Is he/she riding clipless pedals? And does he/she have the correct crankarm length? Crankarm length is an issue. Most small frames come with 170mm crankarms...because most of the industry doesn't go shorter than 170mm. But...someone riding a 48cm Cervelo probably has a inseam south of 28.5". Such a person should be using 165mm cranks (because that's the shortest standard crankarm length). However...ideally, a person with legs that short, should get custom cranks in the range of 155mm.

    Shorter cranklength and clipless pedals that allow you to ride closer to the ball of your foot will eliminate toe overlap on Cervelo bikes (at least, the ones I either own, owned, or have put some time in the saddle on).

    Interestingly, my 49 cm bike with 172.5 cranks (in my avatar) has no toe overlap. I actually kind of expected that it might, but it doesn't.

    I'm not sure, because she got the bike used (and she has since moved abroad), but based on her riding style (she has a relatively low cadence and puts massive torque on the cranks with big gears--even up mountains), I would think that if anything the crank length is a little on the long side. I am certain they are not shorter than 170s. They could very well be 172.5. All I know for sure about the components is that she hated them, because she's a Campy fan and the bike came with Shimano parts. I think she rides a 48 or 50. Here's a picture of her from this season. Her saddle is a little low there. She'd only had the bike for a few days by the time of the picture, but that doesn't affect the toe issue, which you can kind of see even though she's not quite at 3 and 9 on the cranks.



    She didn't have any toe overlap on her old TCR.

    I'm not saying Cervelos suck or anything. I'd love a 52cm TT bike (P2, P3, or *drool* P4!). It's just that for some reason this older Cervelo didn't live up to the company's goals.
