ROTOR bottom bracket BB30 | 3024 MTB Ceramic
The ROTOR bottom bracket BB30 to BB24 allows the installation of conventional BB24 cranks in frame with BB30 housings. Thus, an assembly of older cranks in the new framework is possible - by the way also increases the selection of their desired crank. The bearings used have ceramic balls that minimize due to a significantly higher hardness and smoother surface friction in the bearing and to increase the durability. The silicone seals enhance these properties, because they better keep dirt and water. Compatible with Shimano and Rotor cranks.
