This Cassette is part of Shimano's ground-breaking R7100 series. This road cassette is constructed with durable steel cogs and an aluminium spider for maximum strength and reliability. It also features an 11-34T ratio, which makes it ideal for everything from sprinting on the flat to climbing steep inclines on your road bike. Its refined 12-step gear combination also ensures excellent efficiency, so none of your effort is wasted. You’ll experience faster, smoother shifts under maximum torque (pedalling force) and shifts so smooth you’ll barely notice them, whether you're biking uphill, downhill, or rolling on the flats. This is thanks to Shimano’s Hyperglide Plus technology.
