A road cassette designed for efficiency

True to the reputation of the Ultegra range, the 10-speed cassette combines lightweight construction with high durability.

Compatible with standard Shimano/SRAM freehub bodies, the Ultegra 10-speed cassette integrates seamlessly with Shimano 105, Tiagra, and of course, Ultegra groupsets. It’s an excellent choice for an upgrade or a reliable replacement.
