Shimano Ultegra R8000 11-Speed Cassette 11-25T CSR8000125

Shimano Ultegra R8000 11-Speed Cassette 11-25T Shimano's Ultegra range has always been a marker of high design and performance quality. For reliable riding at the front end of the group, and putting in the occasional performance, the Shimano Ultegra R8000 11-Speed Cassette 11-25T is that low range cassette for riders in great shape, or simply for that longer, flatter ride. Weighing just 246 grams, this solidly machined rear cassette is forged and conceived with a greatly improved tooth head shaping, leading to better engagement and, crucially, better practicality when shifting. A Hyperglide EV technology driving weight downwards to that 246-gram headline figure, this is a lightweight, high paced rear cassette, allowing you to reach your fastest speeds, and forcing you to turn higher averages. Made for use with 11-speed Shimano HG-EV chains, this 11-25 tooth 11-speed cassette is an ideal choice for the rider going to take things to the next level, and make a good show of the ride they set out to own.
