Magura MDR-P Rotor Disc Brake

No reviews
 The MDR-P are only for use with Magura MT5e and other Magura eSTOP models. These rotors are top of the line, 60656 specially reinforced to provide increased lateral rigidity and heat resistance with reduced vibration. Great for any fast and/or heavy eBike, including eCargo Bikes. 
Available in 203mm and 220mm

MDR-P Rotors

Optimized for use on e-bikes, these new brake discs provide enhanced performance and stability – and they also reduce vibration.

The MDR-P is a rotor for performance-oriented riders and tough tasks ranging from downhill to e-bikes and heavy cargo bikes. The two-piece rotor saves weight and is also available with a 220 mm 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 new technology, the MDR-P is the most powerful rotor in the MAGURA portfolio, yet it still offers riders low weight and reduced vibration.

The 220mm diameter rotor generates around 10% more braking force than a 203 mm model and 20% more than a 180 mm 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.
