Magura Storm 6 Bolt Rotor
For the past 15 years Magura has been gaining experience in the development and production of disc brake rotors for off road mountain bike use. The Storm rotor's unique shape and strategic drilling (to help clear debris and shed heat) are perfect examples of Magur's expertise come to fruition.
These are the only rotors that I buy individually. Works with Magura, Formula, and Avid brakes. Much less change of the howl.
