Dynamic Chain Engagement (DCE) is used to hold the chain and help prevent chain jump out. This is achieved by using a broader and taller tooth profile in conjunction with a special hooked leading edge and alternate profiled tooth shaping. This provides superior chain retention, lower driving sound, increased durability and drag to a minimum Hollow gear construction for optimized rigidity, lightweight and durability Durable teeth using a plated steel construction supported by a carbon composite (CFRP) carrier body HG 12-speed chain compatible Available in 28T/30T/32T/34T/36T

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.
