SHIMANO ULTEGRA 12-speed HYPERGLIDE+ racing cassette With the ULTEGRA R8100 12-speed cassette you can shift smoothly on the climb, in the sprint and during pleasure trips, without worrying about your next gear step. Larger drive wheels make the drive more efficient and suitable for both Shimano 11- and 12-speed freehubs. HYPERGLIDE+ cassettes offer a revolutionary off-road shifting system with seamless shifting at both extremes of hot range. Now it's time for technology to change road cycling too. Even with maximum effort on a climb or in a competition with a friend, you don't have to slow down to change gear. Shimano ULTEGRA R8150 drivetrains offer maximum efficiency in every gear thanks to the larger sprockets and are still suitable for existing HYPERGLIDE freehubs. In addition, ULTEGRA CS-R8100 cassettes now have 12 gears and are the new benchmark for shifting on the road. FEATURES
