Magura Storm SL.2 6-Bolt Lightweight Disc Brake Rotor - 160mm / 180mm

Featherweight design meets high-performance braking bite. The Magura Storm SL.2—available in 160mm and 180mm diameters—is the ultimate lightweight one-piece disc brake rotor engineered specifically for Cross-Country (XC), Marathon, and Down-Country riders who want to shave grams without sacrificing safety or modulation.

Evolving from the legendary Storm SL, this second-generation rotor combines an aggressive, highly ventilated cutout pattern with structural mechanical stability, providing excellent pad bite, rapid cooling, and reliable performance in both wet and dry conditions.

• Available Diameters: 160mm and 180mm (Select your size)

• Mounting Standard: 6-Bolt (International Standard - mounting hardware included)

• Main Advantage: Exceptional weight-to-performance ratio for XC and Marathon racing

• Rotor Thickness: 2.0 mm (Magura standard durability)

• CicloBottega Perk: Factory original Magura component, fast express shipping!

In-Depth Description

Shave grams, maintain control: maximize your cross-country efficiency with the ultra-lightweight Magura Storm SL.2 160mm and 180mm brake rotors.

In cross-country racing, every gram counts, particularly when it comes to rotational weight on your wheelset. However, compromising on braking power is never an option when tackling modern, highly technical XC World Cup tracks. The Magura Storm SL.2 is engineered to deliver the perfect middle ground: a minimalist, heavily skeletonized steel profile that strips away unnecessary material while retaining the thermal capacity and structural rigidity required for reliable, high-speed decelerations.

Optimized Cutout Pattern for Heat and Debris Cleansing

The distinct, wide cutouts across the Storm SL.2's braking track serve a dual purpose. First, they dramatically increase the surface ventilation, allowing the rotor to shed heat instantly during brief, intense braking efforts. Second, the edges act as a self-cleaning mechanism for your brake pads, sweeping away mud, dust, and water film on the first rotation to guarantee an immediate, predictable bite right when you grab the lever.

Genuine Magura Durability

Unlike many fragile aftermarket "tuning" rotors that measure a thin 1.5mm to 1.8mm, Magura maintains their signature 2.0mm thickness even on the lightweight Storm SL.2. This ensures excellent lateral stability, high resistance to warping under thermal stress, and a significantly extended wear life. It pairs seamlessly with Magura's MT series (such as MT8 Carbon, MT4, or MT Race setups) but serves as an exceptional lightweight upgrade for any 6-bolt system.

Key Features

• Ultra-Lightweight Engineering: Significantly lowers rotational mass on the hubs for faster acceleration and crisper climbing.

• Pro XC Race Proven: Developed directly alongside elite Marathon and Cross-Country racing teams.

• Magura 2.0mm Standard: Thick profile avoids the fluttering, bending, or quick wear-down common to generic ultra-light rotors.

• Outstanding Heat Dissipation: Generous ventilation slots prevent hot-spot glazing on the brake pads.

Shipping and Mechanic's Installation Advice

CicloBottega dispatches this component inside flat original factory packaging, fully shielded by an external box to prevent any micro-bending or warping during express transit.

Mechanic's Tip: When installing lightweight rotors like the Storm SL.2, cleanliness and precision are critical. Thoroughly clean your hub mounting face and the rotor itself with isopropyl alcohol before fitting. Tighten the 6 mounting bolts in a cross/star pattern using a torque wrench calibrated precisely to 4 Nm (over-tightening can warp the lightweight carrier arms). For XC racing, we highly recommend pairing this rotor with fresh Magura organic pads (Performance or Race compound) and performing a proper bedding-in process to achieve maximum bite and completely silent operation on the trail.
