The Press Fit 4124 will easily fit into your carefully selected gear with its press fit, 41mm diameter and 24mm axle bottom bracket shell. ROTOR conceived its Universal Bottom Bracket (UBB) concept to eliminate the complicated bottom bracket and crank compatibility challenge that has increasingly frustrated its LBS mechanics.
