Shimano Ultegra 6600 cassette suitable for 10-speed systems. This Shimano cassette provides perfect shifting performance, even in the most extreme and demanding of conditions. The largest chainrings are mounted on a lightweight aluminium spider which saves weight and pushes the stiffness to an optimal level.
