Magura Storm SL 6 Bolt Rotor
The Storm SL 6 Bolt Rotor is the lightest Magura brake rotor ever. To make it, Magura took the Storm rotor and gave it a serious diet to whittle away grams. The main change being the Storm SL has large, polygonal shaped vents and the Storm has smaller, round, drilled holes. The Magura Storm SL 6 Bolt Rotor comes standard on the Magura Marta brake but is a suitable lightweight replacement rotor for most disc brake calipers on the market regardless of manufacturer.
