Your height is mostly irrelevant. Fit is based more on inseam (not clothing inseam, but inseam floor to "sitbones", aka isheal tuberosity), torso length, arm length. Regarding the inseam measurement, my clothing inseam is about 30 inches/76.2 cm. My inseam measured as described is 32.5 inches/82.55 cm.

For fun, go to www.wrenchscience.com and www.competativecyclist.com and plug accurate measurements into their fit programs. This will give you an idea of how fit is done, but I doubt it's as good as an expert human helping you in person. Good luck.
