I might be looking to get a new bike and am wondering whether a double or a triple would be appropriate. I ride a triple right now, 32/42/52 I think, havent gone into the small ring once and Ive had it since feb. Not even on the hills around here in N. Va. I go to school out in AZ so dont have to worry about hills period there really. Even if I do encounter hills, wont a 39 ring be easier than the 42 I push up hills? Also, I did the wrench science measurement program. I was just wondering if anyone has found that to be pretty good in terms of measurements or if it is way off? good starting point? Im going to test ride the bike, if I seriously consider it, but I would like a starting point for frame size.
