da Vinci triple crankset & BB tech questions
I'm currently in the process of replacing our old Campy Record triple crankset (54/44/36) in favor of a da Vinci (52/39/30) due to the fact that our aging years are catching up to us. However, when I attempted to put on the new da Vinci set, I've noticed that our current spindle is far too long by perhaps 10mm to 15mm if not more. The BB shell is a standard 68mm, but I'm wondering if there are any others here who might be using essentially the same da Vinci set and if you'd happen to know what length of a spindle to use? As it is now, the front derailleur is unable to reach the middle and outer chainrings. Also, our current BB is a Phil Wood model from the 80s, so will I need to purchase a completely new BB and spindle? Since I haven't had much experience in the BB area, I'd appreciate any help. Thanks in advance!
Edit note: I might also add that da Vinci recommends a spindle range of 107mm to 113mm for the stoker, so I'm thinking that a 110mm might be about right. I do know, though, that without taking the crank back off the bike that the current spindle must be about 130mm or longer. It's quite a significant difference, to say the least. Thanks again!
