The CeramicSpeed BB30 Bottom Bracket for Shimano Road delivers ultra-low friction and optimized power transfer for riders seeking maximum drivetrain efficiency. Designed to adapt BB30 frames for Shimanos 24 mm axle, it uses a precisely machined aluminium threaded system that threads into itself for a secure, stable fit.

Built Around CeramicSpeeds World-Class Bearings: Each bottom bracket comes equipped with CeramicSpeeds hand-built bearings, engineered to outperform traditional systems with smoother rotation and greatly extended lifespan. This ensures consistent power delivery across long rides, racing efforts and demanding conditions.

Two Bearing Options for Performance Customization: Riders can choose the standard bearing setup, which uses hardened-steel races paired with super-round CeramicSpeed Balls to reduce drag and extend life. For even greater durability and lower resistance, the coated version adds a 3-micron metallic layer to the races for improved smoothness.

Low Friction and Long-Term Reliability: Both bearing options offer significantly reduced friction compared to typical bottom bracket systems, enhancing speed and efficiency with every pedal stroke. The design also improves resistance to contamination and corrosion, ensuring reliable performance in all environments.

Ideal for riders wanting the smoothest possible interface between Shimano cranks and BB30 frames, this bottom bracket delivers long service life and exceptional efficiency.
