Product Information

Full details

The Magura MDR-C CL 180mm disc rotor is engineered specifically for e-bike riders and daily commuters who demand high stability and consistent stopping power. Its reinforced one-piece design features an additional connecting ring that effectively minimizes vibrations and increases structural stiffness, making it a reliable choice for trail and city bikes alike. While it provides excellent performance for electric bicycles, users should note that this specific version is optimized for quick-release axle systems and requires a centerlock-compatible hub.

FAQs

Is this rotor compatible with non-Magura brakes?

While optimized for the Magura MT-family, it is generally compatible with most disc brake systems, provided the brake pad width is compatible with the rotor's track.

Can I use this rotor with a thru-axle hub?

No, this specific model (MPN 2702236) is designed for quick-release axles; you should look for the thru-axle version if your bike requires it.

Do I need a special tool to install this?

Yes, you need a centerlock lockring tool that engages with the internal splines of the lockring.

What is the weight of the 180mm version?

The 180mm MDR-C CL rotor weighs approximately 190 grams.

Is the lockring included in the box?

Yes, this version includes the lockring designed for quick-release axles.

Why is this better for e-bikes?

The MDR-C features an extra connecting ring that adds stiffness and heat resistance, which is necessary to handle the higher weight and speeds of electric bicycles.

Troubleshooting

Brake squealing or noise

Clean the rotor surface with a high-quality disc brake cleaner and verify that the pads are not contaminated with oil.

Rotor rubbing against pads

Check that the wheel is seated properly in the dropouts and perform a caliper alignment to center the pads over the rotor.

Loosening after installation

Verify the lockring is tightened to the recommended torque specification using a proper internal tool.

Pros and Cons

Pros

  • High structural rigidity for stable braking
  • Effective noise and vibration reduction
  • E-bike optimized for durability
  • Secure centerlock mounting system
  • Wide compatibility with Magura MT brakes

Cons

  • Requires centerlock-compatible hub
  • Specific to quick-release axles
  • One-piece design is not modular

Setup, Compatibility & Care

Installation requires a centerlock lockring tool that engages with the internal notches of the included lockring. Ensure your hub is centerlock compatible before installation.

  1. Slide the rotor onto the centerlock splines of the hub.
  2. Thread the lockring by hand to ensure it is not cross-threaded.
  3. Use a torque wrench with the appropriate internal tool to tighten the lockring to the hub manufacturer's specifications.

For care, periodically check for signs of scoring or uneven pad wear. Keep the braking surface clean of oils and debris; if the rotor becomes contaminated, use dedicated brake cleaner. Avoid touching the rotor surface with bare hands, as natural oils can reduce braking efficiency and cause noise.
