Shimano Ice Tech Freeza RT-EM910 CL Internal brake disc

SHIMANO Ice Tech Freeza RT-EM910 Center Lock Disc Brake Rotor

Elevate your ride and experience unparalleled braking control with the SHIMANO RT-EM910 Center Lock Disc Brake Rotor, the pinnacle of stopping power for modern MTB Cycling and high-performance E-Bikes. Engineered specifically to meet the intense demands of heavier, faster electric mountain bikes, this disc brake rotor delivers consistent, fade-free performance on the longest and most challenging descents. When control and confidence are paramount, the RT-EM910 stands as the ultimate upgrade for any serious rider.

Unmatched Cooling for Supreme Confidence

The core benefit of the SHIMANO RT-EM910 lies in its revolutionary heat management system. By leveraging SHIMANO´s groundbreaking ICE TECHNOLOGIES FREEZA design, this rotor dramatically reduces heat buildup in your braking system. This superior heat dissipation translates directly into a more consistent lever feel, predictable stopping power, and a significant reduction in brake fade, even under sustained, heavy braking. Ride with the assurance that your brakes will perform as powerfully at the end of a descent as they did at the top, allowing you to push your limits with maximum safety and control. This advanced cooling also contributes to a longer lifespan for your brake pads, saving you money and maintenance time.

Engineered for E-Bike Dominance

The RT-EM910 isn´t just a powerful brake disc; it´s a smart, integrated component designed for the modern E-MTB ecosystem. A key feature is the integrated magnet system, making it perfectly compatible with SHIMANO STEPS and other e-bike speed sensors that require a wheel magnet. This clean, robust integration eliminates the need for extra, easily damaged magnets clipped to your spokes, ensuring a reliable speed reading and a streamlined aesthetic. Combined with its robust construction, the RT-EM910 is built to handle the increased torque, speed, and weight inherent to electric-assist mountain biking, making it the definitive choice for e-bike enthusiasts seeking peak performance.

Main Features:
