Magura MDR-P CL Disc Brake Rotor – 203mm CenterLock. The Magura MDR-P is a disc rotor for performance-oriented riders and tough tasks ranging from downhill and ebikes to heavy cargo bikes. It features Dovetail Interlink technology a patented interlocking of the outer and inner rings. This provides additional support for the inner ring if the outer ring expands due to heat. In contrast to floating discs the torque is transmitted to the dovetail-shaped toothing over its entire surface instead of just the rivets increasing the rigidity of the brake disc and the degree of heat dissipation under continuous load. The MDR-P is the most powerful brake disc in the Magura portfolio yet it still offers riders low weight and reduced vibration. Perfect for demanding applications such as ebike or downhill riding. Two-piece design offers the highest level of heat dissipation and high torque transfer. Wear optimized ring design. Prepared for tone wheel or magnet.
