Token Ninja TF38624 BB386/392 Ceramic Bottom Bracket For Shimano Crankset

The Ninja TF38624 is crafted to banish creaks and vibrations from your drivetrain. Its precise construction and material design deliver a quieter, smoother ride that enhances both comfort and performance.

Fusion Construction for Rigidity: This bottom bracket uses Fusion technology that blends aluminum with composite materials. The combination forms a stable shell that fits securely in your frame, minimizing movement and translating rider input efficiently through the drivetrain.

Robust Bearing Support: The bearings are housed in an alloy shell to provide a solid, supportive platform. By extending the shell across both sides of the hub, the design enhances structural stiffness, unifying the frame, cranks and bottom bracket into one strong assembly.

Sealed Protection with X-Seal: To maintain consistent performance, the Ninja TF38624 incorporates Token’s X-Seal system. This advanced sealing technology keeps contaminants such as dirt and water out while minimizing friction, preserving optimal bearing function over time.

At its core are TBT bearings, featuring ceramic balls paired with ultra-hard races. This design offers exceptionally low rolling resistance and exceptional durability for extended use under demanding conditions.
