Ok, so i bought myself a new school Mongoose 1 piece crank, and while trying to bolt on my chainwheel, found that my bottom bracket set doesn't screw on. Its close, but obviously the wrong thread. I haven't got any new school stuff, and don't know about when they changed thread sizes etc. Who can tell me if I buy a new bottom bracket set, will the bearings fit into old school cups that I've already fitted into my 1988 Haro sport, or have they went and messed around with bearings sizes as well?
Why can't these young uns just leave things as they were?. Things were certainly different before the changes...rant:
