T47/T47a Ceramic PowerSet Bottom Bracket for Shimano characteristics

• • PowerSet Technology. By taking into consideration the behaviour of a bearing when it is under load we have designed a bottom bracket that reduces power loss by up to 20%.

• • Preloaded System. All the balls come into contact with the bearing, distributing the force over a larger surface area. By doing this, we reduce friction and minimise wear.

• • Angular Ball Contact Bearings. They support both axial and radial loads.

• • Unibody design. Ensures the parallelism and concentricity of the bottom bracket.

• • Fully sealed. Axial seals on bearings and fully sealed on all surfaces, to avoid water or dust.
