Riding hard, pushing for that better time? The Shimano Ultegra R8000 11-Speed Cassette 11-25T gives you those low toothed sprockets that get your rear wheel spinning faster.

For the rider looking to tackle flatter days on the bike, this 11-speed cassette is perfect for ramping up the pace, whilst delivering that strong drive, and seamless shifting.

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.
