OK, this is embarrassing, but I can't remember exactly what my current TT is. It is written down somewhere.
But, I do remember that after my fitting and measuring my current bike (which seems to fit pretty well), the bike shop folks and I decided that when I go to test ride, I am probably looking to test 49's in men's bikes, and 52's in women's.
I know my current bike (a man's bike) is bigger than a 49, but it also has much more relaxed geometry and HT length, etc, than the 49 I am thinking of testing. So, maybe the more aggressive position makes the smaller frame seem more reasonable?
I am 5'6" with a 29" inseam.
