You had your choice of any bike in the shop but you made your selection based on potential upgrade options. The Press Fit 4124 will easily accommodate your handpicked rig with its press fit, 41mm diameter with 24mm axle BB shell. ROTOR conceived its Universal Bottom Bracket (UBB) concept to eliminate the complicated bottom bracket/crank compatibility challenge that has increasingly frustrated the mechanics at your LBS.

Crafted with an advanced, precision CNC-machining process, every unit guarantees a flawless fit within the frame, eliminating creaks and ensuring perfect alignment. This meticulous manufacturing results in a bottom bracket that is not only incredibly robust but also contributes to the overall stiffness and responsiveness of your bike. Integrated labyrinth seals create a sophisticated barrier against dirt, water, and other contaminants, protecting the high-quality bearings from the elements. This advanced sealing technology significantly extends bearing life and maintains that out-of-the-box smooth feeling ride after ride, regardless of the weather conditions.
Designed for broad compatibility and ease of use, the PF4124 is the definitive answer to many common compatibility questions. It is engineered specifically to work seamlessly with frames featuring BB86, BB89, and BB92 bottom bracket shells and is optimized for use with both ROTOR and Shimano 24mm cranksets.
