CeramicSpeed BB ALPHA

This bottom bracket is specifically designed for frames with an 86mm shell width and a 41mm shell diameter (BB86 standard) and is compatible with SRAM DUB spindle interfaces. Please verify your frame's bottom bracket standard before purchasing to ensure a proper fit.

The BB ALPHA uses grade-3 Silicon Nitride ceramic balls, which are significantly harder and smoother than standard steel bearings. This reduces friction and rolling resistance, allowing your drivetrain to spin more freely with less energy input.

Yes, the bearings are serviceable. You can clean and re-grease them to maintain peak performance and extend the lifespan of the unit, which is a key advantage over many sealed, non-serviceable bottom brackets.

Absolutely. The BB ALPHA features custom light-contact seals and precision dust covers specifically engineered to keep moisture and debris out of the bearing races, ensuring reliability even in challenging road conditions.

By utilizing 7075 aluminum cups, the BB ALPHA keeps the total weight down to 76 grams. It offers a lightweight construction without sacrificing the durability or structural integrity required for high-performance road riding.
