After trying, manfully ;>, to handle this problem myself, I've realized I'm stumped, and I hope you all can help me.
I want to install a late-ish (mid-80s maybe?) Suntour Cyclone crank on a bike with 130mm spacing. English-threaded. The problem is, I don't have the matching bb for the crank. But I figured I could substitute something. Pre-1990 Campagnolo square-taper bb spindles don't work in this crank, they bottom out. I haven't tried a Shimano yet, but that's next.
I'm avoiding getting a Phil bb since they are so expensive, but assuming I did get one, which taper do I look for? JIS? And how long should the axle be?
So, my question is two-fold: first, what taper will work in this crank? and, second, how long should the spindle/axle be so that a double-chainring will clear the chain-stay?
Thanks for any help you can provide, on list or off.
