Ceramic bearings are significantly harder and smoother than steel, which drastically reduces friction in your drivetrain. This allows your cranks to spin more freely, saving you watts and improving efficiency during long rides.

Yes, the BB ALPHA is built for durability in harsh environments. It features custom-engineered seals and precision dust covers specifically designed to keep moisture and contaminants out of the bearings, ensuring smooth rotation even in demanding conditions.

Installation requires a standard press-fit bottom bracket tool compatible with the BB86 standard. Because the unit uses a simplified spacer tube and lightweight aluminum cups, the installation process is straightforward for anyone comfortable with basic bike maintenance.

The hardened stainless-steel races provide superior corrosion resistance compared to standard steel. This ensures the bottom bracket maintains its performance and longevity, even when exposed to sweat or road spray over time.
