Two cassettes enter, one cassette leaves as the evolutionary XX 10-Speed cassette takes center stage with its incredibly lightweight status, precise shifting abilities, and superior Thunderdome-worthy strength. X-Dome CNC-machines together eight cogs from a single block of billet steel. X-Glide technology creates four identical up-shift locations able to be picked up by any outer link for perfect timing and near instant shifting. Open design aids in mud clearance to give you cleaner shifting performance and longer component life, while the aluminum large cog can be replaced as needed.
