Magura MDR-S Avinox Rotor Sensor Integration, No Compromise E-bike riders running Avinox-based drive systems know that a clean, clutter-free drivetrain setup starts at the rotor. The MDR-S Avinox addresses that directly by integrating the Avinox speed sensor tonewheel into the rotor body itself, eliminating the separate sensor disc that otherwise requires its own mounting hardware and cable routing. The rotor still delivers the MDR-S's core credentials: high braking force, good heat resistance, and an optimised friction ring design that stiffens the rotor to 2. 5mm for reduced vibration and quieter operation under load. If you want your Avinox system wired tight from hub to lever with nothing extra bolted on, this is the rotor that makes it happen. Features Avinox tonewheel integrated directly into the rotor body eliminates a separate speed sensor disc and its mounting hardware for a cleaner, lighter e-bike build Optimised friction ring design with 2. 5mm rotor thickness increases rigidity to reduce vibration frequency and brake noise under repeated or sustained braking loads High braking force with good heat resistance handles the elevated thermal demands of motor-assisted bikes and heavier system weights Compatible with all Magura MT-series brake systems slots into existing Magura hydraulic setups without adapter changes Mineral oil system compatibility pairs with Magura's Royal Blood mineral oil hydraulic brakes - not DOT fluid Specifications Diameter203mm Mount Interface Construction One-piece steel with optimised friction ring design Thickness2. 5mm or 2. 0mm Pad Compatibility E-Bike Approved Yes - Avinox tonewheel integrated Lockring Included Weight Intended Use Trail, All-Mountain, Enduro, E-Bike | Magura | Mdr-S Avinox Rotor 203Mm X 2. 0Mm
