my old Nashbar road bike, CCroMo frame, traditional geometry, is a 21" frameset, or 53cm. That was OK when I was 5'8", but lost an inch due to some ortho issues over the last 20 years, and now when I stand over the bike in cleats, my 'bits' are resting on the top tube, which makes mounting and dismounting the bike very awkward.

On a side note, when looking at framesets for Kestrel and Kuota, I use standover height measurements from their geometry charts to give myself 1-2" of clearance, and oddly, the top tube lengths of their frames fall precisely into the lengths calculated with the formula I mentioned.. so I guess whatever Lemond was thinking, so were a lot of frame-makers.. even to this day. I seem to fit well on a "small" frame withabout a 20-21" top tube. This usually leaves me with a good saddle position, 165-170mm crank arms, and a 100-110mm stem @ 0 degree rise.

It is quite possible that I am a mutant however. I've been compared to worse. hehe
