Hope V4 Vented Disc Rotor 220mm 6 Bolt Cycling Bike Performance

Designed specifically for Hope V4 brakes. The Vented Rotor is highest performing disc for the harshest operating conditions. The outer is constructed from three pieces to create a gap between the external braking surfaces to help reduce heat build up. Features The vented rotor is designed specifically for V4 brakes.. Highest performing disc, for the harshest operating conditions.. Outer is constructed from three pieces to create a gap between the external braking surfaces.. The rotor uses internal fins to allow the air to flow between the two friction parts, the induced air flow significantly reduces heat build up in the rotor.. Fantastic and consistent braking performance in wet conditions thanks to its capability to clear the water layer through its fins.. Dyno tests show up to 15% less heat build upcompared to our floating rotors.. Vented outer is joined to aluminium centre allowing 1 of freedom in a true floating design.. Specification Size: 220mm. Thickness: 3.3mm . Mount: 6 bolt.
