Grabbing a fistful of brake on a steep descent only to find overheated rotors squealing and skipping underneath you is not a feeling any of us enjoy. It’s tricky, alternatively, to find the right balance between quick cooling, powerful, and a large braking area. The Magura Storm HC 6-Bolt Rotor strikes the easiest balance between beefy and light, borrowing characteristics from both the Storm and Storm SL to succeed in a happy medium with the power to stop you dead in your tracks, and cool quickly, so you do not end up with anodized rotors at the end of a hairy downhill. Adore it’s siblings, the Storm HC is made from X30Cr12 steel, and uses a beefy width of 2mm for stiffness and reliability. The HC seems to pick out and select positive characteristics from the SL and original Storm in the case of braking surface and cooling properties. Instead of the circular cuts of the usual Storm, the Storm HC uses oval cuts akin to the Storm SL, enabling improved cooling on the ride, but opts to use fewer cutouts. This change does result in a bit more weight, but at the gain of braking power and stiffness, making it stronger and more reliable than the SL.
