Silly question time

(1/1)

southern andy:
Sorry chaps, please excuse my ignorance, new to this game again.

Ok, bottom bracket size.

I see on E bay and on other sites, that when one is advertised the seller puts in Euro or USA. I'm assuming they are both different sizes. Are all BMX bottom brackets on a frames the same size ?? So would a USA bottom bracket fit into a standard BMX?? or is it just the cranks that have too match the said bottom bracket.

Have i explained myself correctly, i think i've just confused myself big time now.

Trev:
different frames take different style bottom brackets.
you will need to check what type yours takes.
i believe the old style is the US BB, but now you also have Mid, Euro & Spanish.

SaMAlex:
This is a cool site, and if you scroll down a bit there is a big section all about BBs. I dont totally agree with what he concludes but it shows all the sizes nicely.
