Magura Storm Rotor

Storm - The ultimate disc brake rotor. For the last 15 years Magura has been gaining experience in the development and production of disc brake rotors for the demanding off road use on mountain bikes.

Combining the wealth of our experience and the latest results of our mission perfomance, we have achieved a maximum of stopping power, control and ventilation at a minimum weight (10% weight saving compared to old model). One look is enough as the cool design says it all: the STORM will set a new benchmark when it comes to weight, performance and durability!


Magura Storm Rotor Features:


Basis of development:

  • 15 years experience in the development of disc brake rotors for the demanding off road use on mountain bikes.
  • Intense product development in conjunction with Mission Performance supported by modern analysis and calculation software as well as intensive testing on our high-tech test facilities.
  • Modern and continuously improved production methods.
  • Intense real world testing by world class mountain bikers the most demanding race courses as well as on thousands of training kilometres our home trails around the Swabian Alb and the Alps.


  • Optimised rotor geometry for extreme temperature absorption without disc warping.
  • Perfect friction balance between brake pad and rotor for maximum braking power in all conditions, even after extremely long and difficult descents.
  • Wider brake surface prevents tipping of brake pads. This optimises brake modulation without squeaking or brake pad judder.
  • Bigger surface for optimised heat dispersion through more cut outs.
  • Through latest FEM-calculations optimised transitions between brake surface, spoke and fixing ring. Therefore massive weight reduction by equally high stiffness.
  • Optimised production processes creating zero fault rate and therefore allowing further refinements and weight savings without sacrificing strength and durability.
  • Reduced wear compared to old SL rotor

Result: The STORM rotor currently sets the benchmark in deceleration, modulation and cooling at a minimum weight.
