The Galfer Shark Evo 6 Bolt Rotor Black represents the pinnacle of modern mountain bike brake engineering. Designed specifically for the demands of aggressive trail, enduro, downhill, and high-torque e-MTB riding, this rotor builds on Galfer’s revolutionary Shark design by introducing a semi-rigid floating construction. The high-carbon stainless steel braking track is laser-cut to maximize surface area, allowing it to work seamlessly with all pad shapes while aggressively clearing mud, water, and trail debris via its distinct Wave outer profile.
At the heart of the Shark Evo is an aerospace-grade 7075-T6 aluminium carrier featuring a stealthy black-anodised finish. Joined to the outer friction ring using robust 8mm hollow rivets, the floating structure accommodates high thermal expansion without warping or buckling. Internal cooling fins actively draw heat away from the caliper pistons, keeping fluid temperatures low during extended alpine descents. Enhanced lateral stiffness ensures precise, symmetrical pad contact to prevent uneven wear and eliminate brake fade when you need stopping power most.
Whether you are retrofitting a heavy-duty e-bike or upgrading your gravity rig, the Galfer Shark Evo includes integrated speed sensor magnet mounting holes for full e-bike system compatibility. Its stealthy black finish seamlessly integrates into any cockpit and frame colorway, making it as visually striking as it is technically capable.
Two-Piece Floating Construction: Heavy-duty 8mm hollow rivets connect a high-carbon stainless steel braking track to a lightweight 7075-T6 aluminium core, allowing controlled thermal expansion.
Shark Fin Cooling Technology: Integrated internal fins dissipate heat rapidly under heavy braking, maintaining consistent lever feel and preventing pad fade.
Sleek Black Anodised Finish: Durable black anodising on the central spider resists corrosion and complements any custom bike build.

✅ Enduro & Downhill Racers: Exceptional heat management prevents brake fade on long, steep, high-speed descents.
✅ E-MTB Enthusiasts: Thicker 2.0mm profile and high lateral stiffness handle the higher momentum and braking loads of electric bikes.
✅ Stealth Build Fans: The clean black-anodised carrier delivers a subtle, premium look that blends perfectly with any bike setup.
❌ Centre-Lock Wheel Owners: Designed for standard 6-bolt hubs and requires a Centre-Lock adapter for spline hubs.
❌ XC Weight Weight-Watchers: The extra mass of a 2.0mm floating rotor prioritizes cooling and stiffness over ultralight cross-country performance.
❌ Kashima Finish Seekers: If you want your rotor carrier to match your Fox Factory suspension legs, choose the Kashima version instead.
The Galfer Shark Evo features a 2.0mm rotor thickness (thicker than standard 1.8mm options). Before installing new brake pads with this rotor, ensure you use a plastic tire lever to push your caliper pistons all the way back into their housings. Once installed, perform a thorough bed-in process—roughly 10–15 moderate stops from 20 km/h followed by 5 firm stops—to transfer pad material evenly onto the steel track for whisper-quiet performance and maximum initial bite!
