Ultegra CS-R8101 12-Speed Cassette

HYPERGLIDE+ cassettes have brought a revolution to off-road shifting with smooth up and down gear changes. Now, this amazing technology is transforming road cycling. Whether you're pushing hard uphill or racing a friend, you don't need to ease off to shift gears. The Shimano ULTEGRA R8150 drivetrains, with larger cogs, boost efficiency in every gear and are still compatible with existing HYPERGLIDE FREEHUB bodies. With 12 gears, the ULTEGRA CS-R8100 cassettes set a new standard for road shifting.

Using this cassette is a breeze. Just install it on your compatible bike following the standard installation process. When riding, you can shift gears smoothly without reducing your effort. Remember to keep your chain clean and well - lubricated for the best performance. Also, check the cassette regularly for any signs of wear or damage. If you notice any issues like rough shifting or visible wear on the cogs, it might be time to replace the cassette. When storing your bike, try to keep it in a dry place to prevent rust on the cassette.
