Sram Derailleur GX DH 7 Speed Medium Cage

The SRAM GX DH 7-speed rear derailleur (Medium Cage) is a purpose-built gravity component designed for downhill racing and bike park riding. Built to handle high speeds and rough terrain, it delivers precise, quiet shifting with maximum chain stability when it matters most.

Engineered with SRAM’s proven X-Horizon™ design, it minimises unwanted movement, reduces shift effort, and eliminates “ghost shifting”—keeping your drivetrain consistent on rough descents. The roller bearing clutch further stabilises the chain, reducing slap and noise so you can stay focused on the trail.

The medium cage layout is optimised specifically for DH setups, offering the right balance of chain tension and ground clearance for aggressive riding.
