Prime's PF30 Bottom Bracket rams a lot of technology into a small package to keep your cranks running smoother for longer. At Prime we use the best elements from different materials to ensure optimum performance.

Product description

Creak-Free Bottom Bracket

The bearings are held in place by an alloy cup, but in order to keep the BB and frame quiet and creak-free, they are housed in a plastic/nylon shell. Finding the right mix of plastic and nylon has allowed us to precisely manufacture these BBs so they won’t deform over time or when they get wet. It also allows the BB to fit in frames that aren’t perfectly aligned.

Our bearings inside our PF30 BBs are precisely manufactured to spin smoothly, and when combined with our special seals, repel the elements. The seal is made from a mix of rubber and alloy to provide double protection for the bearings. And, we hand assemble these bottom brackets to ensure none of this development and precision is wasted.
