CeramicSpeed PF30A Bottom Bracket

This specific model is designed for frames with a 46mm shell diameter and a 73mm shell width. It is built specifically for the PF30A standard, so please verify your frame's specifications before purchasing to ensure a proper fit.

This bottom bracket is engineered for cranksets utilizing the SRAM DUB spindle standard, which features a 28.99mm spindle diameter. It will not work with standard 24mm or 30mm spindles.

CeramicSpeed uses ceramic balls that are harder, rounder, and smoother than steel, which significantly reduces friction and drag. This results in a more efficient power transfer and increased durability over the life of the component.

No, this bottom bracket is designed to fit directly into your frame's PF30A interface without the need for adapters. This direct-fit design helps eliminate potential creaking and ensures a more stable, quiet ride.

The integrated dust cover creates a tight seal that prevents dirt, grit, and moisture from reaching the bearings. This protection is crucial for maintaining the bearing's longevity and performance, especially when riding in wet or dusty conditions.
