I currently have a 50cm Nashbar Steel Cyclocross bike and the fit feels perfect to me. The stem is almost slammed (1 spacer under it) and close to horizontal. The seat is as far back as it will allow on the rails. I found that I like my knees behind KOPS. KOPS = knee pain for me. Here is the geometry for the bike. Sorry for the poor quality, it's the best I could find.



The Nashbar bike is my commuter. I'm looking to get a road bike and like the Motobecane Le Champion Ti. I understand very little about bike geometry but as I'm comparing, it seems that size 48 is the closest match to my current bike. Hoping those of you who really understand bike geometry can confirm or correct me.


Thanks! BTW, I'm 5'6" (barefoot) with a 29" inseam.

If you like your fit now, I think you'd be fine with the 48 Le Champ Ti.
