V3 Disc Technology
The patented V3 attachment uses a retention ring that holds the hat and disc together. The ring means no need for torque wrenches, no hardware and no hassle. The ability to change a disc quickly and efficiently saves time and effort. As well as being convenient, the new V3 technology is much lighter than previous designs, making it easier to put on and pull off. This V3 rotor retention method is based on the use of a two-turn retaining ring, which is held in a groove in the hat that overlaps the rotor flanges effectively locking the rotor to the hat.
