SRAM XX Eagle Transmission XS-1297 12-Speed Cassette

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.
