CS-R7101 105 12-Speed Cassette 11-34T – High-Performance Shimano Road and Gravel Cassette

The CS-R7101 105 12-Speed Cassette is Shimano’s high-performance cassette designed for both road and gravel cycling. Featuring Hyperglide+ technology, this 12-speed cassette ensures precise, smooth shifting, even under load. The specially contoured shift gates are computer-engineered to provide faster, more efficient gear changes, allowing riders to maintain momentum, especially during challenging climbs or sprints.

This cassette has an 11-34T gear range, offering close ratio gearing that allows for more efficient energy use through finer cadence control. The largest sprockets are mounted on a lightweight alloy carrier, reducing overall weight while increasing rigidity for maximum performance. Additionally, the sprockets are cut away and drilled to further minimize weight without sacrificing strength.

With a nickel-plated finish, the CS-R7101 offers excellent resistance to corrosion, ensuring long-lasting durability. Designed for use with Shimano’s super-narrow 12-speed chains, this cassette is compatible with a wide range of road and gravel bikes, making it a versatile choice for performance-focused cyclists.
