Engineered for riders who demand reliable, consistent braking across all terrains, the Shimano SM-RT70 Center Lock Disc Brake Rotor is a premium upgrade designed to deliver precision stopping power, exceptional heat management, and quiet performance under pressure. Whether you're riding gravel, road, XC trails, or all-mountain terrain, this rotor guarantees peace of mind with every squeeze of the brake lever.
🔥 ICE TECHNOLOGIES: Advanced Heat Control for Peak Performance
At the heart of the SM-RT70 rotor is Shimano’s proprietary ICE TECHNOLOGIES—a multi-layer rotor construction that dramatically improves heat dissipation. Featuring a sandwich design of stainless steel outer layers bonded to an aluminum core, this innovation reduces surface temperatures by up to 100°C under aggressive braking. The result is:
Minimized brake fade during long descents
Enhanced pad life and rotor longevity
Stable, predictable braking feel across varying trail and weather conditions
ICE TECHNOLOGIES ensure your braking performance stays cool-headed, even when the terrain gets fiery.
🛠️ CENTER LOCK™: Fast, Secure, and Hassle-Free Installation
Designed with Shimano’s CENTER LOCK™ interface, the SM-RT70 features a spine-and-lockring system that allows quick rotor mounting with a single cassette lockring tool. Compared to the traditional 6-bolt system, CENTER LOCK provides:
Faster, tool-friendly setup and removal
Superior rotor centering for consistent brake alignment
Enhanced rigidity under high braking forces
External serration lockring included for broad compatibility
Perfect for mechanics and riders who value convenience and reliability in equal measure.
