Available only for the Moto V2 brake, the Hope V2 Vented Rotor takes braking performance to a new level. Using the same proven floating design as other Hope rotors and advanced manufacturing techniques, the internal fins allow the air to flow between the two friction parts. The induced air flow significantly reduces and delays heat build up in the rotor. Dyno tests show a difference in temperature of 15% between a standard floating rotor and a ventilated floating rotor. The rotor also gives a better and more consistent braking performance in wet condition thanks to its capability to clear the water layer through the fins. If you want to abuse your brake in endless descents this is the rotor for you.
