Product information "ULTEGRA CS-R8101 12-speed Cassette"

The Shimano CS-R8101-12 is the matching 12-speed cassette for the new Ultegra R8100 and GRX RX820 groupset. The advanced drivetrain is 100% focused on performance and is a real revolution thanks to HYPERGLIDE+ technology. Compatible with HG Spline L2 road 12-speed and HG Spline L road 12/11-speed freehub body.

THE SCIENCE OF SPEED: Shimano Ultegra 12-speed Cassette CS-R8101-12

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.

HYPERGLIDE+ cassettes revolutionized off-road shifting with its seamless shifts both up and down the gear range. Now it's time for the technology to change road cycling. Even during maximal efforts up a climb or racing a friend, riders no longer need to back off to perform a shift. In any gear, Shimano ULTEGRA R8150 drivetrains maximize efficiency thanks to larger cogs and retain compatibility with existing HYPERGLIDE FREEHUB bodies. All this while increasing to 12-gears, ULTEGRA CS-R8101 cassettes are the new paradigm in road shifting.
