CeramicSpeed Bottom Bracket T47 86mm Inboard

The CeramicSpeed T47/86 Inboard Coated Bottom Bracket is designed to install 24mm spindle cranksets, including Shimano and other compatible systems, into T47 threaded frames with an 86.5mm shell width. It provides a low-friction bearing interface for modern road and gravel builds using the T47 standard.

This inboard configuration positions the bearings within the frame shell for a compact and efficient installation. The coated bearing version features a 3-micron metallic coating applied to the bearing races, designed to reduce friction, improve smoothness, and extend service life compared to standard bearings.

The bottom bracket is compatible with 86mm T47 frames, including select Trek T47 85.5mm frame standards. It is supplied as a complete system with installed CeramicSpeed bearings and the necessary installation components.
