Better heat dispersion than current road disc systems.
Shimano Ultegra RT800 Ice-Tech FREEZA CL RotorWith 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 LaterThe 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.Features: Material: Aluminium (inner), Steel (braking surface) Compatibility: Shimano Centerlock hubs Mount Type: Centerlock Recommended Use: Road Brake Compatibility: All Shimano road bike disc brakes Lockring Included: No Manufacturer Reference Code: SMRT800SS Weight: 128 g (160 mm) 108 g (140 mm)Technologies: Ice Technologies FREEZA: The power and precision of Ice-Tech FREEZA are unmatched. With an increased surface area for heat dispersion, the Ice-Tech FREEZA rotor has achieved the ultimate in heat control. A proven 50°C 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.A 2-year warranty is offered with all Shimano products from Chain Reaction Cycles (3 years on Dura-Ace and XTR products).Buy Shimano Components from Chain Reaction Cycles, the World's Largest Online Bike Store.
