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. 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.
