The Shimano SM-RT86 6-Bolt Disc Brake Rotor is engineered with Ice Technology to maintain consistent braking performance, even during intense and extended descents. This cooling innovation reduces rotor temperature for stable, reliable braking every time. Three-Layer Clad Rotor Construction: A stainless steel-aluminum-stainless steel sandwich structure improves heat dissipation while reducing overall rotor weight. The aluminum core quickly transfers heat away from the braking surface, protecting pads and maintaining efficiency. Enhanced Heat Management and Longevity: By effectively reducing rotor fade, this rotor allows for more confident braking in high-speed and high-load conditions. Lower temperatures extend pad life, reduce brake noise and offer a more controlled braking experience. Optimized for All Conditions: The mud-shedding rotor blade design prevents buildup, making it ideal for mixed-terrain riding and adverse weather conditions. Whether you're hitting the trails or navigating mountain roads, this rotor delivers dependable performance. The 6-bolt mount pattern ensures compatibility with a wide range of hubs, making it a top choice for serious mountain and trail riders.
