THE SCIENCE OF SPEED: Shimano Ultegra 12-speed Cassette CS-R8100
Great speed means great responsibility. That's why, faced with the task of making the new ULTEGRA groupset even faster, Shimano decided to take a holistic and 100% performance-focused approach. Shimano's new 12-speed road groupset delivers unparalleled control and comfort anytime, anywhere - whether you're competing in an amateur race, chasing your personal best, or out for a social ride. That is "Science of Speed". And it's what sets SHIMANO apart from the rest.

The smooth shifting of the ULTEGRA R8100 12-speed cassettes lets you climb, sprint or roll along without having to think about the next change of speed. Larger teeth maximise drive efficiency and are at the same time compatible with existing 11-speed freewheels. The cassette is available in two versions: 11-30T and 11-34T.
