SHIMANO ULTEGRA R8000 11-SPEED CASSETTE 11-25T, 11-28T 11/25

Eagerly anticipated, the updated Shimano Ultegra R8000 range has arrived. Shimano has evolved the Ultegra series, which hugely benefits from the joys of trickle-down technology from its big brother, Dura Ace R9000. Infused with Shimano’s ‘rider-tuned philosophy’, this Ultegra R8000 11-Speed Cassette offers a huge range of gear ratios to help you conquer any terrain.


SHIMANO ULTEGRA R8000 11-SPEED CASSETTE 11-25T, 11-28T 11/25

The Shimano Ultegra R8000 11-Speed Cassette 11-28T is part of Shimano’s greater diversity and versatility within their Ultegra range. With improved tooth shaping and Hyperglide shifting technology assuring you of smoother travel up and down your rear cassette, this is a fantastic choice for the rider looking for a decent range in their setup.

With the Ultegra range aiming to provide the rider with better than ever customisation, the Shimano Ultegra R8000 11-Speed Cassette 11-28T gives the considered rider the ability to get their gearing right for the conditions and contours they need to scale.

Taking you right down to the smallest, standard 11-tooth sprocket and ranging up to a still rather strong 28-tooth sprocket for scaling slopes, this cassette is conceived using Shimano’s Hyperglide technology, bringing weight downwards to a 246 gram level without compromising the rigid structural integrity of your rear cassette.

Compatible with 11-speed Shimano HG-EV chains, this cassette features a redesigned tooth shaping and enhancing engagement and pickup, making shifting smooth and responsive whilst leaving transmission direct.
