Bottom Bracket help needed
« on: April 26, 2011, 10:59 PM »
Hi,

I am new to bmx builds and need some help. I have bought a 86 PK ripper frame and forks to build and have been getting a few bits and bobs. So I just got hold of a Profile racing 3 peice crank and now I need a bottom bracket. I know the spindle axel is 19mm and if I knock the old cups out of the frame the inside frame measures 52mm.

can anyone advise what kind of BB I need, or are they generic for all frames and just the axel size differs?

cheers Jason

Will be a US bb .. any cup that size will fit .. spindle sizes differ, should be pretty easy to find a Profile bb for that  :daumenhoch:
