Hi
I'm planning to build a winter training road bike,
just wondering what is the diameter of the bottom bracket measuring without the thread.
e.g. BB's two ends, but measure below the threads.
because I've got a old frame and not sure if today's BB will fit.
it have a 68mm length and ~34.5mm diameter 'hole' for the BB.
