Magura USA Storm SL 6-Bolt Rotor
The Storm SL 6 Bolt Rotor is the lightest Magura brake rotor ever. To make it, they took the Storm rotor and gave it a serious diet, whittling away some serious grams. The difference is that the Storm SL has large, polygonal shaped vent holes rather than the Storm's smaller, round drilled holes. The Magura Storm SL 6 Bolt Rotor comes standard on Marta brakes, but it can also be used with their Louise brakes. The gentle sawtooth shaping on the outside diameter decreases the chances that you'll experience brake squeal. It comes with fasteners and will work with any 6 Bolt compatible hubs.
