The revolutionary Sram XX mountain bike cassette uses the same techniques that produced the PowerDome road cassette. With X-Dome eight of the cogs are CNC-machined together out of a single block of billet steel creating an incredibly lightweight precise and strong cassette like none other. The aluminum large cog can be replaced as needed. X-Glide is the common denominator that gives XX its unmatched shifting performance. With X-Glide all four upshift locations are identical and can be picked up by any outer link. This open design aids in mud clearance allowing a cleaner shifting performance and overall longer component life. Compatible with Sram and Shimano 10 speed systems 11-32 185 grams. 11-36 208 grams.
