Shimano Ultegra CS-6700 Cassette

The Shimano Ultegra CS-6700 cassette is the benchmark in the 10-speed performance road bike world. As part of the beloved 6700 group, this 10-speed cassette offers an exceptional balance between low weight and Ultegra's characteristic durability. The largest sprockets of the CS6700 are mounted on a lightweight aluminum spider. This significantly reduces the total weight (approx. 230 grams for the 11-25T), while improving stiffness, resulting in more efficient power transfer and a smoother feel when accelerating.

The core of Ultegra's performance lies in Shimano's HyperGlide (HG) technology. The computer-optimized tooth profile and strategically placed shift aids ensure that the chain moves quickly and precisely from one sprocket to another, even under the high load of a sprint or a steep climb. This smooth shifting is crucial for maintaining a consistent cadence and minimizes wear on the chain and cassette. The sprockets themselves are made of steel with a nickel finish, which ensures a high degree of wear resistance and corrosion protection.

The Shimano Ultegra CS6700 is designed to cover a wide range of gear ratios, with options ranging from narrow racing ratios (such as 11-23T) to wider ratios (up to 12-30T), suitable for mountainous terrain. This makes the cassette very versatile and widely applicable for various road cycling disciplines. The reliable 10-speed cassette is the ideal choice for riders who want the proven performance and low weight of the Ultegra line, and guarantees a long lifespan and consistent shifting performance.
