Rotors for Centerlock

Centerlock

— the system developed by Shimano, in which the brake disc is attached to the hub not with screws, but using a splined washer and a central lock nut, similar to cassette attachment. This installation method simplifies mounting and dismounting, requiring only a special remover (cassette tool), and ensures precise centering of the disc. The system is often used in modern medium and high-end road and MTB bicycles.
