PressFit 30 Bottom Bracket with ABEC-3 Bearings

This is a replacement for frames using a PF30 BB standard. It also fits on frames using BB386EVO, Specialized Carbon OSBB, and BBRight Press Fit standards. Given the dimensional differences of those standards, the appropriate cranks will need to be used (386 crank won't work in a PF30 BB on a PF30 frame, etc). 

Grade 10 chromium steel balls, within 10/1,000,000" round, are used in chromium alloy steel races to give you noiseless, smooth, long bearing life.
