Compatible standards: SHIMANO BB 86/92 Color: Black This product is fixed by screwing on the inside, which prevents the BB from twisting and prevents squeaks. In addition, a resin ring is placed on the frame adhesive surface to increase adhesion and rigidity, and also to prevent noise. The bearings are made of ceramic and rotate smoothly. Also, no special tools are required; you can turn it with a BB wrench for SHIMANO Hollowtech 2.
