  • Shimano Ultegra RT800 Ice-Tech FREEZA CL Rotor

    With its highly advanced construction and technologies, the Ultegra RT800 CL (Centerlock) hydraulic disc brake rotor shows that Shimano is adding enhancements to its entire product range. It’s constructed with an aluminium inner section and a durable steel braking surface that has Shimano’s Ice-Tech FREEZA design. This lightweight and durable road bike brake disc brings you reliable performance and prevents heat build-up on long descents, giving you fade-free braking power.

    Ride Faster, Brake Later

    The Ice-Tech FREEZA design provides constant braking performance through better energy control. Combined with Shimano's Ice-Tech FREEZA pads (sold separately) the disc's surface temperature drops rapidly when braking consistently at speed, which is a great improvement in braking performance and reliability over traditional brakes. This means you can leave the brakes until the last possible moment.

A proven 50&degC reduction in heat gives the user consistently powerful brakes for the duration of the ride, increases durability throughout the whole disc brake system, and provides longer pad life.
