SRAM XX1 Eagle CS-XG-1299 12-speed cassette stands as the pinnacle of gear range options, offering cyclists an unparalleled 500 or 520-percent range with its expansive 10-50 or 10-52 tooth span. This broad spectrum allows stronger riders to opt for larger chainrings, enabling higher speeds without compromising on climbing capabilities. Athletes find themselves spending more time in the higher gears of the cassette, where power transfer is at its most efficient and gear wear is significantly reduced. Built on the industry-leading X-Dome™ architecture and compatible with the proven XD™ driver body, it not only promises exceptional durability but also offers backwards compatibility, broadening upgrade possibilities for existing Eagle™ setups. The cassette is a common choice among the world’s elite, having been part of numerous Olympic, World Cup, and World Championship victories, and is an ideal match for XX1 Eagle AXS™ components. Embracing the full spectrum of the Eagle™ Colorsystem, the XG-1299 cassette is available in Black, Gold, Rainbow, and the striking new Copper finish, making it a crowning touch to the world’s most prestigious and coveted bicycles.
