Despite riding seriously -- about 6,000 miles/yr -- for over 20 years, I apparently have some kind of obsessive-compulsion thing about always fooling with my bike fit. (95 changes -- NOT a typo! -- last year alone.) Seems to get worse every year. Before resigning myself to this being a "mental" thing, anyone know if it's possible there may be a physical reason for this? For instance, I use the "hands-off" test to determine the seat's fore/aft; I find it very hard to believe that some "mental condition" could result in me being able to pass the test with a 6 cm -- tip behind BB -- setback one day, then a few days later, I can't pass it unless the seat is 9 cm back!!! And, yes, I've had several bike fittings. (It's soon after those that I REALLY went nuts changing things due to the resulting loss in efficiency and/or pain.) The fitters seem to be confused, too! The range of their fits includes:
seat height (BB-seat): 81-82 cm
seat setback (BB-tip): 5.5-9 cm
bar reach (tip-bar): 53-56 cm
bar drop: 5-8 cm
After changing positions, it feels much better for a few rides. Then, on one ride, the fit suddenly feels so screwed up, its as if I'm on someone else's bike! I then recheck things, discover something has to be changed by a centimeter or 3. Then it feels WAY better -- and is usually WAY faster -- until a few days later, when something is obviously wrong . . . and so on, and so on.
So, any ideas as to why -- besides the mental thing? Anything to try? If it helps, I'm 6'2" with an inseam of about 36". My torso is pretty short, relative to my legs, and I think my thighs are on the short side relative to my lower legs. (Guess I could average out all the fittings, and see how that works.) I realize I may need a sports psychologist more than a bike fit expert, but I don't have the time or money for that!
