XG-1275 Eagle C1 Cassette 12Spd 10-50T XD Black

The SRAM XG-1275 Eagle is the 12-speed mountain cassette for riders who want wide-range gearing without moving to a Transmission drivetrain. This C1 version covers 10-50 teeth across twelve cogs, a 500 per cent spread that keeps a usable jump between gears while still giving a low climbing gear. It mounts to an XD driver body only.

Construction follows SRAM's FULL PIN approach, with steel cogs held together by high-strength stainless steel pins. The open structure between the cogs mirrors SRAM's X-DOME cassettes and helps clear mud, which supports cleaner shifting and longer component life in wet conditions. The cassette runs with SRAM Eagle 12-speed rear derailleurs and Eagle chains, not Eagle Transmission T-Type parts.
