Includes Replacement Rotor only (Hat not included). Price is per rotor. The V3 design features an all new retention ring that holds the hat and disc together without the need for traditional nuts & bolts.

The 2-turn retaining ring is held in a groove in the hat that overlaps the rotor flanges, effectively locking the rotor to the hat.
