Magura MDR-P E-Bike Disc RotorOffering fantastic strength and reliability for a wide range of mountain bike (MTB) disciplines, this disc brake rotor benefits from a tough steel and alloy construction. It is also electric bike (E-bike) ready with a build that’s tough enough to handle the increased speed, torque and braking force that’s produced by E-bikes. Coming equipped with a range of technologies to improve performance, this is a perfect choice of upgrade for when it’s time to replace your own or worn-out existing brake rotor.The MDR-P is a rotor for performance-oriented riders and tough tasks ranging from downhill to e-bikes and heavy cargo bikes. Compared to the MDR-C, the two-piece rotor saves weight and for the first time it is also available with a 220mm diameter. A special feature of the two-piece disc is the patented interlocking of the outer and inner rings (Dovetail Interlink technology). The interlocking provides additional support for the inner ring if the outer ring expands due to heat. In contrast to floating discs, the torque is transmitted over the entire surface instead of just the rivets. The result is increased rigidity of the brake disc and heat dissipation that is much more effective under continuous load. Thanks to this technology, the MDR-P is the most powerful rotor in the Magura portfolio, yet it still offers riders low weight and reduced vibration. Perfect for MTB gravity use.Magura offers a rotor with a diameter of 220mm for the first time, the MDR-P. This rotor generates around 10% more braking force than a 203mm model and 20% more than a 180mm model, for the same manual force. The higher mass also reduces the risk of brake fading and reduces brake pad wear by 15%. The temperatures that are critical for the brake pad are reached much later by the MDR-P rotor.Please note: There are multiple diameters available for this rotor. Please choose the option to match your braking setup from the menu.Features: Material: Steel/Alloy Use: Mountain Bike (MTB) and Electric Mountain Bike (E-MTB) Mount: 6-bolt Optimised for electric bikes, rigid and resistant to vibrations Single or Pair: Single Weight: 241gManufacturer’s Part Number: 2701938 Silver 203mm 2701939 Silver 220mm 2701937 Silver 180mmBuy Magura Components from Chain Reaction Cycles, the World’s Largest Online Bike Store.
