Sram Derailleur GX 2x 11 Speed Long Cage Max 42T

The SRAM GX 2x11 long cage rear derailleur is a proven workhorse designed for riders running a 2x11 drivetrain setup who need wide gear range, durability, and consistent shifting under load. It brings SRAM’s performance-focused technologies into a rugged, trail-ready package.

Built on the X-Horizon / X-Actuation platform, it delivers smooth, precise shifting with reduced chain slap and improved stability on rough terrain. The integrated roller bearing clutch keeps the chain tight and controlled, making it ideal for technical trails and mixed conditions.

This version supports cassettes up to 42T max, giving you a wide climbing range while maintaining efficient shifting performance across both chainrings.
