BlackBearing bottom brackets offer superior performance and quality thanks to their BBlock system. These two-piece bottom brackets with CNC-machined aluminium cups guarantee greater rigidity, allowing for optimal bearing alignment even under heavy loads. This ensures longer-lasting performance with less creaking. The bearings can be replaced while retaining the aluminium structure of the bottom bracket, reducing long-term maintenance costs.
Featuring ceramic bearings, this bottom bracket delivers remarkably superior smoothness while saving weight compared to steel bearings. The bottom bracket is compatible with Italian-style threaded bottom bracket standard frames, with a width of 68 mm to 73 mm. It allows the installation of cranksets with a 24 mm diameter axle (Shimano, Rotor, FSA, etc.), and Sram/Truvativ GXP cranksets thanks to an adapter supplied with the bottom bracket.
