Gearing is what gets you going forwards. Get it wrong and you can find gaps across your rear cassette where you feel mismatched against your own bike, Making an informed choice on your riding style and stature then is important, and in the Shimano Ultegra R8000 11-Speed Cassette 12-25T, you can be afforded a crafted and narrow breadth of gearing, catering perfectly for those flatter, longer days on the bike.

Riding at pace and picking up your speed, this 246-gram rear cassette is designed for use with Shimano’s HG-EV chains, improving speed and accuracy of transmission as you ride.

Implementing Hyperglide technology in the shaping too, you can be assured of a far smoother experience in flicking through your rear cassette. Transmission direct and engagement honed into the design of this cassette, you can be sure of riding at your optimum.
