SRAM XX Eagle SL Transmission XS-1299 12-Speed Cassette

   Gears 1 – 9–        Hardened steel X-Dome architecture

   Gears 10 – 12–        All-aluminum Spider Cog

   X-Dome™–        X-DOME technology creates an incredibly lightweight, precise and strong cassette. The open design aids in mud clearance, giving you cleaner shifting performance and longer component life.

   12-Speeds–        10 / 12 / 14 / 16 / 18 / 21 / 24 / 28 / 32 / 38 / 44 / 52

   520% Gear Range–        The 52 tooth cog steps down with improved gear progression with 44 and 38 tooth cogs in the low end (compared to the Eagle drivetrain 10-52-tooth cassette)

   X-Sync Chainring–        SRAM X-SYNC 1x chainrings provide the highest level of performance and durability. The SRAM X-SYNC tall square teeth edges engage the chain easier than traditional triangle shaped teeth. The sharp and narrow tooth profile, as well as rounded chamfer edges, help manage a deflected chain. To provide the best possible performance in muddy conditions, the X-SYNC chainrings have been designed with mud clearing recesses for the inner chain links and rollers.
