The Galfer Shark Evo 6 Bolt Rotor Raw represents the pinnacle of heavy-duty mountain bike braking performance. Building upon Galfer's proven Shark design, the EVO version incorporates a floating two-piece construction featuring a laser-cut high-carbon stainless steel braking track connected to a precision CNC-machined carrier via robust 8mm hollow rivets. This floating structure accommodates thermal expansion, maintaining optimal lateral alignment and reducing warping under extreme temperatures.
The bare metal 'Raw' finish highlights the intricate CNC machining of the aerospace-grade 7075-T6 aluminium spider, delivering an industrial aesthetic that pairs seamlessly with any custom build. Engineered with an expanded surface area, internal cooling fins, and a 2.0mm thickness, it drastically lowers operating temperatures to extend brake pad life and eliminate thermal fade on prolonged downhill runs.
Designed for modern hard-charging setups, the rotor features high lateral stiffness for symmetrical piston actuation and an integrated magnet recess for e-bike speed sensors. Its aggressive Wave profile sweeps away water, mud, and trail debris to ensure a sharp, consistent bite across all riding conditions.
Two-Piece Floating Design: Connects a high-carbon stainless steel friction ring to a 7075-T6 aluminium core using 8mm hollow rivets for superior thermal expansion control and lateral stiffness.
Shark Fin Cooling Technology: Integrated inner cooling fins aggressively dissipate heat, reducing operating temperatures and preventing brake fade on long descents.
Raw CNC Finish: Precision-machined aerospace-grade aluminium carrier showcased in an unpainted silver finish for a clean, technical look.
Mounting Standard: 6-Bolt

Claimed Weights: 180mm (165g), 203mm (195g), 223mm (225g)
Core Material: CNC-machined 7075-T6 Aluminium
Track Material: Laser-cut High-Carbon Stainless Steel
E-Bike Compatibility: Yes (includes integrated speed sensor magnet hole)
✅ Extreme Downhill & Enduro: Exceptional thermal capacity prevents lever fade on long, steep, or high-speed mountain descents.
✅ E-MTB Ready: The robust 2.0mm thickness and built-in speed sensor magnet recess suit the extra weight and demands of modern electric mountain bikes.
✅ Custom Raw Aesthetic: Uncoated silver CNC carrier provides an industrial, custom-milled look that complements any frame colour.
❌ Centre-Lock Hub Owners: Designed specifically for 6-bolt mounting interfaces and will require adapters for Centre-Lock hubs.
❌ XC Weight-Savers: Cross-country racers seeking ultra-light rotors may find the reinforced 2.0mm construction heavier than minimalist options.
❌ Stealth Black Preference: Riders wanting an all-black stealth build should opt for the Black Anodised version of the Shark Evo.
Because the Shark Evo rotor features an extra-thick 2.0mm profile, ensure your brake calipers have enough clearance and reset your caliper pistons fully inward before installing new pads. Pair these rotors with metallic or sintered compound pads for high-load downhill and e-MTB use, or resin pads for quieter operation and immediate initial bite on trail rides.
