The Shimano CS-R8000 Ultegra 11-28T 11-Speed Cassette is a high-performance Hyperglide (HG-EV) road cassette developed for Shimano Ultegra R8000 11-speed drivetrains. Designed to deliver smooth, fast, and precise shifting, it features optimised sprocket tooth profiles and shift ramps that provide seamless gear changes under load.
Constructed using a combination of nickel-plated steel sprockets mounted on lightweight aluminium carriers, the CS-R8000 offers an excellent balance of low weight, durability, and stiffness. The 11-28T ratio is a popular choice among road cyclists, offering closely spaced gears for maintaining an efficient cadence while still providing a low enough gear for moderate climbs. It is fully compatible with Shimano DURA-ACE, Ultegra, and Shimano 105 11-speed road drivetrains. (productinfo.shimano.com)
