The Magura QM9 brake adapter enables the seamless and precise installation of a 203 mm brake rotor on the frame’s rear mount (WSS / IS). Designed for mountain bikes and e-bikes where high braking performance and precision are top priorities.
Maximum braking power with a 203 mm rotor
Boost your braking system’s efficiency by upgrading to a larger rotor. The QM9 adapter precisely positions the brake caliper relative to the 203 mm rotor, ensuring improved heat dissipation, a firmer lever feel, and full control on steep descents.
Lightweight design and included mounting hardware
Machined from durable aluminum alloy, the adapter ensures a rigid connection without adding unnecessary weight to the bike. Dedicated mounting bolts are included, allowing for immediate and secure installation on the frame.
