Built for harder trail use and longer service life, this updated 6-bolt brake rotor delivers stronger, more consistent braking than the previous version. Its 2.2 mm thickness adds stiffness, heat capacity, and durability compared with standard 1.75 mm rotors, helping it stay dependable through steep descents and heavy braking. The new 200 mm size replaces the long-running 203 mm option, while the 220 mm version offers Shimano’s highest level of braking power for riders who want maximum control on demanding terrain.
