quick TT frame size question. (3 size choices)
 

im 6'1" with a 33.5" inseam and i very comfortably ride a 56cm road bike with a 56cm top tube. i used to have a 58cm frame and it felt too big. the 56 bike feels amazing.

would the correct size TT/tri frame for me have a top tube length of: A. 52.5cm, B. 54cm, or C. 56cm.

ive always heard the general rule of thumb is to go 2cm shorter than your road frame, but im just making sure i buy the right size. :thumb:

disclaimer, i know the bike might not be the EXACT PERFECT fit for my body, but in the price ball park im playing in, i dont have too many options.

thanx guys.
