Mount your Maguras.

Unless you are attaching your Magura brake to a 160mm post mount on your fork, you'll need a Quick Mount Adapter, known by the acronym QM. Magura decided with the proliferation of choices available to riders, it made the most sense to provide the brakes without brackets and have the customer choose the right bracket(s). Below you'll find a guide to determine which is right for you.

  • QM5 bracket -- 203mm rotor with front IS mounts
  • QM7 bracket -- 203mm rotor with 160mm Post Mounts front or rear
  • QM8 bracket -- 203mm rotor for (RockShox BoXXer)
  • QM9 bracket -- 203mm rotor with rear IS mounts
  • QM10 bracket -- 180mm rotor with rear IS mounts
  • QM11 bracket -- 160mm rotor with front IS mounts, or 203 mm rotor with front IS 203mm mounts (Fox 40)
  • QM12 bracket -- 180mm rotor with front IS mounts, or 160mm rotor with rear IS mounts
  • QM20 bracket -- 180mm rotor with 160mm post mount front or rear

Unanswered Question

I have confirmed with Magura that I will need the QM42 for my Pike 160mm fork if I would like to use the Storm SL 203mm rotor. What I am not sure about is the compatibility of the QM42 with my caliper, I am using an SRAM Guide RSC caliper. Will the mounting holes align?

Not much to say, it does what it's supposed to

Will the QM26 adapter work to convert 180mm post mount to 203mm post mount? I have a 2016 Fox float 36 and want to use a 203mm rotor. The Shimano SM-MA-F203P/PM is out of stock everywhere (including here at backcountry for 9 weeks!).

That is a great question. I have done some homework on your disk brake adapter question, and looks like you need the SM-MA-F180, P/P Front adapter for that fox 36 fork. If you have any additional questions, please feel free to e-mail me at dmyers@backcountry.com .
