Prime PF30 Bottom Bracket with Ceramic Bearings black

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

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 prime 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. Prime´s bearings inside the PF30 BBs are precisely manufactured to spin smoothly, and when combined with the special seals, repel the elements. The seal is made from a mix of rubber and alloy to provide double protection for the bearings.

With Prime´s ceramic bearing option, friction is reduced meaning less energy is required to turn the cranks, they're also more durable, and don't rust so they'll require less maintenance. If you're a rider seeking out every possible advantage over the competition, the ceramic option can help take your performance to the next level.
