Shimano Ultegra CS-R8000 Cassette 11-25T 11 Speed

This lightweight 11-speed cassette features a rigid carbon and aluminium spider to transmit force efficiently. That means all your pedaling power gets turned into forward motion. The Hyper glide sprockets are designed with improved teeth shaping to cut down on weight, offer accurate shifting, and reduce wear. Whether you're training on weekdays or racing on weekends, this cassette gives you the right gear combinations for every ride.

Using this Shimano cassette is easy. Just install it on your bike's compatible hub. When riding, shift gears smoothly by using your bike's shifter. For best results, shift gears before you start to feel too much resistance. As for maintenance, keep the cassette clean by wiping it down after each ride. You can use a mild bike cleaner and a soft brush to remove dirt and grime. Also, check the sprockets regularly for signs of excessive wear. If you notice any issues, it might be time to replace the cassette. Make sure to store your bike in a dry place to prevent rust and corrosion on the cassette.
