BB help
« on: April 26, 2011, 11:01 PM »
Hi,

I am new to BMX build and need some help. I have bought a PK ripper 86 frame and have a profile racing 3 peice crank. I need to know what BB to buy, the axle is 19mm and if I knock the old cups out of the frame the frame gap is 52mm. Can anyone help? are all BB's generic to all frame and only the axle measurement differs?

cheers Jason
