What Is It?
The SRAM PG-1210 Eagle 11-50T 12-Speed Cassette is a durable 12-speed mountain bike cassette designed for SRAM's SX Eagle drivetrain and fully compatible with the wider Eagle ecosystem. Featuring an 11-50T gear range, it provides the climbing capability and versatility needed for cross-country, trail, and all-mountain riding.
Unlike SRAM's XG-series cassettes, the PG-1210 mounts to a standard Shimano HG (Splined 8/9/10-speed) freehub body, making it an excellent upgrade for riders who want a 12-speed Eagle drivetrain without replacing their existing wheel or freehub. It utilizes PowerGlide II technology for smooth, dependable shifting and a robust all-steel construction for excellent durability.
