Sram XS-1295 eagle transmission 12 speed cassette 10-52t

The SRAM XS-1295 Eagle Transmission cassette is a premium-level 12-speed cassette developed specifically for SRAM’s Eagle Transmission drivetrain platform. Designed around SRAM’s T-Type shifting architecture, the XS-1295 delivers exceptional shifting performance under load, improved durability, and smoother gear transitions compared to previous Eagle generations.

Built using SRAM’s X-SYNC tooth profiling and full cassette mapping technology, the XS-1295 is engineered to maintain precise chain control and crisp shifting even during high-torque pedaling situations. Unlike traditional drivetrains that shift best under reduced pedaling force, Eagle Transmission is specifically designed to shift smoothly while riders continue applying power.

The cassette uses SRAM’s one-piece X-DOME steel construction for the larger gear cluster, paired with a lightweight aluminum largest cog to reduce weight while maintaining excellent long-term durability. The updated T-Type cassette interface improves drivetrain alignment and chain retention while also contributing to quieter operation across the full gear range.

Its wide-range 10-52T gearing provides a massive 520% gear range, making it suitable for everything from steep technical climbing to high-speed descending and racing. Gear progression is also refined to provide smoother cadence transitions between gears.
