I've looked at www.bikefitting.com and Colorado cyclist to figure out my frame size. I also went into a store and had a Trek dealer fit me. I have a 83cm inseam and stand 5'9.5" I came out as a 56 on the Trek. I want to buy a Look which is either L (55) or M (53).
When using the above calculators with my 83cm inseam I should have a C-C size frame of 54 cm and C-T of 55.6 cm.
When I look at the Look geometry they have a real C-C and a virtual C-C.
For example, for the L frame: real C-C = 50.5cm and virtual = 55.7
Q1: Is the L frame too big for me?
Q2: This is puzzling, the C-T (Actual) measurement is 55cm but the C-C (virtual) is 55.7!! Can the C-T actual really be smaller than the C-C virtual?
Thanks
