Rotor BB1 Road Threaded to 24mm Ceramic Bottom Bracket Info
The Rotor BB1 Road Threaded 24mm Ceramic BB is your basic high-tech central movement. It is designed to work with BSA, aka English-Threaded, bottom brackets.
The design starts with two machined-aluminum (7075-T6) cups into which sealed ceramic-ball bearing races are pressed. Sealed bearings are low friction and low maintenance; sealed ceramic-balls are even lower friction and lower maintenance. It’s a marginal gain that can help every second you’re pedaling. It is also a 5g weight savings, 91g vs. he 96g of the steel ball version.
The inner diameter of the bearings is 24mm, which means this bottom bracket is compatible with Rotor’s 3D24 road model. It is also compatible with Shimano road cranks as well as FSA’s MegaExo thru-axle road cranks.
The cups have machined splines that are designed to work with most conventional external bottom bracket tools. The cups also come with a sleeve that seals the bottom bracket internals from moisture seeping down through the frame. The sleeve is designed to work with road bottom brackets, which are 68mm wide.
The Rotor BB1 Road Threaded 24mm Ceramic Bottom Bracket is your standard bottom bracket, just improved.
