The Shimano Ultegra CS-R8100 12-speed Cassette - Consistently seamless and efficient shifting


The CS-R8100 is the first cassette from Shimano's Ultegra road bike series to have 12 sprockets. It features Hyperglide+ technology, which was first tested in the MTB sector and ensures seamless shifting even under heavy load. You can even change gears safely and instantly when pedalling or sprinting. The gradations have been selected to ensure high gear efficiency in all situations as well as optimal acceleration. The enlarged teeth of the pinions also contribute to this. A special plus point is its compatibility: CS-R8100 not only fits on the new 12-speed freehub body, but can also be used with conventional Shimano road freehub bodies. All sprockets are made of steel, with two lightweight aluminium sprocket carriers.

Technology:

Hyperglide+ / HG+
Hyperglide+ is the efficient further development of the Hyperglide system by Shimano. These are shifting aids and specially shaped sprocket teeth that make shifting to larger or smaller sprockets suppler, smoother and quieter. The system of small rivets attached to the side of the sprocket and milled or pressed-in ramps ensures that the chain is already carried along by the next sprocket during the shifting process before it leaves the previous sprocket. Hyperglide+ is optimised for faster shifting and shifting under load and has a more efficient chain connection, holding power and power transfer when combined with a compatible HG chain. Compared to Hyperglide, the shifting time is reduced by one third and the pedal stroke is noticeably reduced. HG+ enables a completely new chain stability and thus offers a safe riding experience.
