The SHIMANO ULTEGRA Cassette CS-R8101-12 12 speed brings to the world of road bikes the same revolution that HYPERGLIDE+ cassettes introduced off-road. Designed for those who love to push hard on climbs, pull on flats, or sprint uncompromisingly, this cassette allows smooth and precise gear changes even under maximum effort, without needing to ease pedal pressure.
