A fair while ago I had a fit done and it suggested I ride a 54-55 (I havent got the exact numbers to hand) top tube with a 90-100mm stem. My question is, is this the same as riding a 57 top tube with say a 70mm stem, or am I missing something? I've got a weak lower back due to a bit of what is medically know as 'shit spine' but the past two years or so since the fit have been a lot better... but it does limit your frame options a touch...
Anyone know?
