Rotor PF4124 (BB89/BB92/BB86) to 24mm Steel Bottom Bracket Info
The Rotor PF4124 bottom bracket kit contains two sets of Steel Bearings in cups so you can install 24mm diameter thru-axle cranks into frames with the BB86, BB89, and BB92 standard.
The kit contains two lathed and heat-treated alloy cups into which steel bearings are pressed. Spacers are included as well. The kit weighs 61g
The cups have an exterior diameter of 41mm to fit the inner diameter of the bottom bracket shell. The shells these cups fit in should be 86, 89, or 92mm in diameter.
The inner diameter of the bearings is 24mm. That matches the exterior diameter of Rotor’s 3D24 cranks. This bottom bracket should fit more than just 3D24 thru-axles. It should fit any crank with a 24mm diameter thru-axle. Shimano’s cranks have this diameter, as do FSA’s MegaExo cranks.
The Rotor PF4124 Steel BB for 24mm thru-axle cranks presses in and impresses.
