Magura MDR-P 180 mm e‑Bike Brake Disc Rotor — 6‑Bolt 6‑Screw Mount, MT‑Family Compatible

This Magura MDR-P rotor is built specifically for e-bike applications and designed to match the MT family of hubs and calipers. With a 6-bolt mounting pattern and a nominal diameter of 180 mm, the rotor comes ready to install with six mounting screws in the box. It is offered in multiple diameters (180 mm, 203 mm, 220 mm), but this listing covers the 180 mm version; do not pair it with a centre-lock adapter.

Will this rotor fit my bike’s hub and caliper?

If your bicycle uses Magura’s MT-family hubs or calipers with a 6-bolt interface, the MDR-P 180 mm rotor is a compatible option. Always confirm your hub has a 6-hole mounting pattern and that the brake caliper clearance is suitable for a 180 mm rotor.

• Mount: 6-hole bolt pattern compatible with standard 6-bolt hubs
• Compatible families: complete Magura MT family components
• Check caliper clearance for 180 mm diameter before installation
• Not compatible with centre-lock adapters—use only 6-bolt mounting

How does the included hardware simplify installation?

This rotor is shipped with six mounting screws sized for the 6-hole interface, so you get everything needed to attach the disc to a matching hub. Using the supplied hardware ensures correct bolt length and fit, which helps achieve secure mounting and proper rotor alignment.

• Box contents: one Magura MDR-P rotor plus six mounting screws
• Bolts matched to rotor thickness and 6-bolt hub pattern
• Reduces the need to source separate hardware
• Follow torque spec from Magura or your hub manufacturer

Which diameter should I choose for my riding style?

The MDR-P series is available in 180 mm, 203 mm, and 220 mm sizes; larger diameters increase leverage and braking torque, while smaller diameters save weight and lower rotational inertia. Select 180 mm when your frame and caliper clearance are limited or when you need a balance between stopping power and weight.

• 180 mm: compact fit, balanced braking and weight
• 203 mm / 220 mm: increased torque for heavier bikes or steep terrain
• Consider rotor size, caliper position, and frame clearance
• Match diameter to your e-bike’s load and expected use

Are there any installation cautions I should know?

Do not mount the Magura MDR-P rotor using a centre-lock adapter—this model is for a 6-bolt interface only. Ensure correct torque on the six screws, clean the rotor surface before first use, and bed in pads per pad manufacturer recommendations to avoid contamination and uneven wear.

• Do not use with centre-lock adapters—6-bolt only
• Torque bolts to Magura or hub maker specifications
• Clean rotor with isopropyl alcohol before assembly
• Inspect for runout and tighten bolts in a star pattern

Who is this for? The Magura MDR-P 180 mm 6-hole rotor is aimed at riders running Magura MT-family braking systems on e-bikes who need a factory-matched, bolt-on disc with included hardware. It suits commuters and recreational e-bikers who require a direct-replacement 6-bolt rotor sized for compact installations, and for workshops seeking rotors pre-packaged with the mounting screws necessary for immediate fitment.
