An oversized 22mm BB spindle that is made from hollow cold forged Chromoly (CrMo) pipe billet that reduces weight while increasing strength and rigidity Oversized, sealed ball bearings make this bottom bracket virtually maintenance-free and efficiently keeps out water, dirt and mud.
The perfect coupling between central pin and pedal crank is ensured thanks to the particular geometry of the two components; this solution also makes it possible to eliminate the potential play between the different materials. To make the bottom bracket more efficient, they also worked on the inner part. Thanks to an elaborate sequence of thicknesses, they were able to obtain an incredibly light axle while offering an absolute response in terms of rigidity. Thanks to the studies conducted by the Campy Tech Lab engineers, material was removed in the zones that could be lightened but at the same time the points of maximum stress were strengthened. Only in this way was it possible to achieve such a high technical value. A careful working out of the dimensions made it possible to maintain the lateral measurements already defined with the "elder brother" Ultra Torque, thus guaranteeing the maximum freedom of movement and reducing the possibility of contact with the shoes.

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. 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.

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.
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.

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.
