Using Rotor's ingenious and versatile UBB System, the Rotor Press Fit BB86 Road or BB89 and BB92 MTB Steel Bottom Bracket system is an ideal adaptor for all Rotor and Shimano 24 millimetre chainsets. Simple and easy to install, durable and also compatible with mountain bike's that have a BB89 or BB92 shell.
The steel design is combined with lathed heat treated alloy cups. This results in a lightweight system that is also incredibly strong.
Extremely rigid plastic cups prevent compression and deformation, leaving you with a stiff and solid base for power transfer.
Non contact labyrinth seals protects the bearings from dirt and results in a very durable unit that also is ultra smooth when spinning.
A black design with laser etched graphics. A sensational addition to your road or mountain bike drivetrain.
