The Ultegra 10-speed cassette offers a wide variation of gear combinations. A better shifting performance is achieved thanks to more robust shifting tolerances. Reworked and updated gear shape improves accurate chain running and increases shifting performance. Aluminium spider for the three biggest gears reduces weight and improves stiffness.
