I have looked this up before, I dont remember the pitch, think it was either 24 or 26, but I do remember its a BSC thread.
And before anyone asks, BSC is British Standard Cycle thread.
I shit you not.

Tis true I have a couple of BSC bottom brackets the pitch on them is 24 :)  When I googled BSC trying to find one did stumble upon a site that had all the bike stuff in a nice look up table.

Cheers guys,

Yeah, BSC is a thread form left over from our great motor bike days.

Just wanted to confirm sizes.
