CeramicSpeed T47/86 Inboard Bottom Bracket for Shimano

The CeramicSpeed T47/86 Inboard Bottom Bracket is engineered to deliver the lowest friction and the smoothest rotation possible. It enhances power transfer through every pedal stroke, giving performance-focused riders a clear advantage on climbs, sprints, and long endurance efforts.

Built for Modern T47 Frame Standards: This bottom bracket combines the oversized benefits of PF30 and EVO386 with the stability of a threaded interface. Compatible with standard 86mm T47 inboard shells and Trek’s 85.5mm T47 frames, it ensures a precise and secure fit across a wide range of premium road bikes.

Perfect for Shimano 24mm Cranksets: Designed specifically for 24mm spindle cranks, the T47/86 system allows Shimano and similar cranks to integrate seamlessly. With the bearings positioned inside the frame width, it boosts stiffness, reduces rotational drag, and maintains smooth, consistent performance under load.

Choose Standard or Coated Bearing Options: Both versions feature ultra-round CeramicSpeed balls and hardened-steel races for superior durability. The Coated version adds a 3-micron metallic layer to the races, increasing hardness, reducing drag further, and significantly extending the lifespan of the bearings.

It installs securely using the BBT-47 tool, giving riders the peace of mind that comes from a threaded system designed for maximum longevity and consistent performance.
