These cast iron rotors are designed for ProAm hubs that require an unique two bolts per flange design. For quick reference, 10 bolt rotors are for five lug hubs and 12 bolt rotors are for six lug hubs. These rotors feature curved vanes which improve the cooling the rotor which increase braking performance and reduce fade. They are available with either a solid or grooved finish. The groove improves braking performance by allowing the gas that builds up under heavy braking to escape. These rotors are directional.
