EBC MD1171XC XC Series Contour Brake Rotor

The EBC MD1171XC XC Series Contour Brake Rotor delivers superior braking performance through advanced engineering and premium materials. This high-performance rotor features a proprietary stainless steel blend that provides up to 10% improved friction effect compared to standard heat-treated stainless steel OEM rotors, resulting in stronger, more responsive braking power.

Key Features:

• High-friction stainless steel construction for enhanced stopping power
• Lightweight aluminum center hub reduces weight by 5-10% compared to stock rotors
• Patented SD-System square-sided button design allows unrestricted thermal expansion
• Six-button drive system optimizes weight reduction while maintaining strength
• Line contact force transmission provides superior durability over point-contact designs
• Maintains flatness and true alignment throughout the rotor's service life
• Extended lifespan—potentially 5-10 times longer than conventional circular-button rotors
• Contoured blade design improves heat dissipation and brake feel

The innovative SD-System square button attachment allows the rotor blade to expand and contract naturally during heat cycling, preventing the distortion and warping common in traditional rotor designs. This engineering advancement means the rotor will remain perfectly flat and true under all operating conditions, with replacement typically only needed due to impact damage or exceeding wear limits after extended mileage. The EBC XC Series represents a significant upgrade for riders seeking maximum braking performance and reliability.
