The CyclingCeramic T47/24 bottom bracket features external bearings and is designed for 86.5 mm T47 threaded frames and Shimano-compatible 24 mm spindle cranksets.
The T47 standard is widely regarded as one of the best bottom bracket solutions available for high-end road and gravel bikes. Thanks to its large diameter and threaded design, it delivers excellent bearing alignment, increased stiffness around the bottom bracket area, and greater reliability than traditional press-fit systems.
This CyclingCeramic model also benefits from high-performance ceramic bearings and an internal protection sleeve that helps reduce water and contaminant ingress. The result is a bottom bracket that combines the serviceability and reliability of a threaded system with the structural advantages of modern oversized frame designs.

FAQ - CyclingCeramic T47/24 Bottom Bracket
Does this bottom bracket fit the Colnago Y1RS?
No. The Colnago Y1RS is not equipped with a T47 frame, but with a BSA threaded frame. For this bike, you need to choose the CyclingCeramic BSA 24 mm version.
Is the CyclingCeramic T47/24 easy to install?
Yes. The cups screw directly into the frame, and the tool included in the box allows you to tighten them properly.
Is the CyclingCeramic T47/24 86.5 mm a good product?
Yes. Its design is based on a wide and stiff standard, with bearings that are well aligned thanks to the threaded interface. With its internal protection, this bottom bracket has all the qualities needed to be among the best choices on the market.
Is this bottom bracket compatible with 85.5 mm wide T47 frames?
Yes. To our knowledge, some brands such as Trek and Winspace use 85.5 mm T47 frames. This bottom bracket can therefore be fitted to these bikes.
Is this bottom bracket compatible with SRAM DUB AXS cranksets?
No. SRAM DUB cranksets use a 29 mm spindle, whereas this bottom bracket is designed for 24 mm spindles (Shimano, Rotor 24 mm, FSA 24 mm, etc.). For a SRAM DUB AXS crankset, you need to use the CyclingCeramic T47 DUB version, specifically designed for 29 mm spindles.
