See my thread for another aspect, where some of these measurements are not even taken in the same place on different bikes.

I too tried to do it "by the numbers" and found a huge discrepency when I actually rode the bikes. Bikes that spec'd out as the right size were too small, and one that was supposed to be too big felt just right (why do I feel like Goldilocks all of a sudden?). Two with very similar specs felt completely different.

BTW, I'm about your size too (5' 10", 175#, 32" inseam) and ended up on a bike with a TT length of 565cm (22.24") and a standover height of 772cm (30.39"). Also, I have long arms, and this bike has a long handlebar clamp.
