Product Info

Upgrade your ride with the SRAM GX Eagle Transmission XS-1275 12-Speed Cassette – the ultimate secret behind impeccable inboard and outboard shifting even under intense pedaling pressure. With its innovative X-SYNC design, the harder you push, the smoother it shifts. Engineered with a 55mm chainline to minimize extreme chain angles, this cassette boasts a 520% optimized range, featuring larger 38 and 44-teeth cogs before the 52-tooth cog for precise gear transitions in the low end.

X-Sync ChainringSRAM 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.

520% Gear RangeThe 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)

Mini ClusterThe Mini Cluster Hybrid cassette construction combines four small cogs that are CNC machined out of a single block of billet steel with an additional eight cogs that are individually pinned together. The result: a cassette that's light, durable, and equipped with a gear range that's perfectly fit for any ride.
