bottom bracket advice
If a Schwinn Super Sport bottom bracket shell measures 65mm, and I'm using a Truvativ BB adapter, what length BB spindle might I need?
I'm planning on double front cranks. One SS will have a Shimano 600, and the other one will be Sun Tour.
(I am renovating two fillet-brazed early '70's Super Sport frames...)
