To make the BB841P a tough bottom bracket, we use the best materials. This means the shell is made from a combination of fibre and plastic. This allows us to machine it precisely and allows it to fit precisely in the frame and eliminate squeaks. It also provides a stable platform for the bearings and gives them a longer lifespan.
In order to make this bottom bracket even more durable we use our patented X-Seals to keep moisture out while keeping drag to a minimum. It also includes a tube that further enhances water repellence. The optional ceramic TBT bearings are extremely hard making the rolling resistance low and saving you precious energy. And since these bottom brackets are hand-assembled, we can be sure that only the most precisely made bottom brackets are ever packaged and sold. Sure, it’s a lot of effort but details matter.
