that makes perfect sense. people question the fit on my girlfriend's bike when it is riderless as well.

she is 5' 8" with an already long 32.5+" inseam. about 1.5in of your 2in height difference is in your legs. here is her bike with a 55cm tt:




what crank length are you running?



on the flip side, i am about 6' 1/2" with a 34in inseam and have a 58.5 ETT and a 120mm stem
