Water Repellent To make our BB86 Bottom Bracket even more durable, we've used special seals, which keep moisture out while keeping drag to a minimum. A tube is also included to further enhance water repellence. Our bottom brackets are hand-assembled, so we can ensure that all our BBs are finished to perfection to keep your bike riding smoother for longer. Ceramic Bearings With our 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.

Low Friction Bottom Bracket Designed so that the bearings rest on the axle of the crank, these BBs provide a straight load to the bearings, which means your BB will last longer. This also allows us to make the Prime Threaded BB with tighter tolerances, so it runs smoother with less friction. This means you'll require less effort to make it up that hill or sprint for the line. To keep our Threaded BB running smoother for longer, we use special seals that keep water out of the bearings. We use multiple smaller seals, which reduces friction and provides a better barrier against moisture and dirt. Our bearings themselves are manufactured to precision and packed with slick, waterproof grease. Ceramic Bearings With our 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.

Our bearings are highly polished so they spin smoother for longer, while the seals protect the bearings and races from dirt and debris that try to make their way in.
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 BB386 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.
