Ready for racing, the superb Shimano R8000 cassette is equipped with 11 steel sprockets which are more than capable of handling all the intensity that comes with all-day events. Using HG-EV technology, this version gives you a rider-tuned gear combination and cadence management. This means you'll benefit from its optimal gear ratio which perfectly suits your riding discipline, so you can blast up to speed in seconds and maintain the edge over your competitors.
Tech Tip: This cassette is compatible with all Shimano 11-speed road derailleurs. However, you should choose the same tooth count as your existing cassette or confirm the maximum cassette capacity for your derailleur before choosing)
Please Note: The 11-34T version of this cassette is the "CS-HG800" model as Shimano does not make the CS-R8000 in an 11-34T version.
