With a focus on decreasing disc brake rotor heat deformation, the result of the new Ultegra Cl800 Ice Tech Freeza Disc Rotor is quieter than ever brake performance without sacrificing weight or heat dissipation.Ultegra grade RT-CL800 Ice Tech rotors give excellent performance made from a stainless steel / alloy 3-layer sandwich construction that manages heat while ridingThe clad steel / alloy / steel rotor construction allows heat generated from braking to radiate quickly through the aluminium core achieving surface temperature drops of around 50 deg C. When used with Ice Tech pads surface temperatures can drop from around 400 to 300 deg C, this provides great improvements in performance all roundIce Tech rotors achieve long pad life, less noise and less fade due to improved heat dispersionUsing the proven Shimano Centre Lock system for excellent rigidity and security with an easy set-upRotor contact surface has been developed for excellent pad clearing and cooling which increases pad performance and lifeLarge forged alloy spider supports rotor surface, increasing rigidity and reducing weightComes complete with alloy lockring

Shimano’s Ultegra range is race focused, but at a more affordable price than the top-tier Dura-Ace line. The R8000 offers 11 sprockets and is available in a broad range of ratios, so whether it’s a tightly packed 11–25-tooth block for time trialing or a wide ranging 11–32-tooth for conquering even the most epic climbs, there’s something for everyone. Tough, Lightweight, Durable Machined from a combination of aluminum and steel, an Ultegra R8000 cassette offers an excellent compromise between weight, durability, and performance. To keep the weight down aluminium is used to rivet the largest three sprockets and a fibre-reinforced composite the next largest two. Tipping the scales at a low of 232 grams for the 11–25T, and a high of 300g for the 14–28T option, regardless of your preferred choice you certainly won’t be weighed down. But, not only is this cassette lightweight and high performing, it is also durable. Corrosion resistance comes via the nickel-plated steel sprockets, so you can ride without the worry your cassette will disintegrate at the sight of rain. A Shift In Performance Aside from weight and durability, the R8000 cassette performs its job well. In fact, there’s virtually an imperceptible difference in performance between it and a higher-spec’d Dura-Ace cassette. Shifting gears is exactly what you’d expect from a component maker as known for precision engineering as Shimano, in one of its top-tier products. It’s quick, smooth, and reliable. Hyperglide technology, the brand’s proprietary system, ensures that even under load you’ll be able to change through the gears. Product Features Lightweight 11-speed HG-EV cassette with rigid alloy sprocket carrier for reduced weight and better shifting performance, even under the most demanding gear changes Hyperglide EV sprockets have been designed to reduce weight and improved teeth shaping provides accurate shifting and reduced wear Wide gear range to meet the demands of all types of rider Optimised for use with 11-speed HG-EV chains, but compatible with all 11-speed drivetrains Please note, due to the current supply situation with many products, aftermarket packaging and manuals may not be supplied.
