Optimized for 1x11-speed mountain biking, the SRAM XX1 Rear Derailleur 11sp with Type 2.1 technology features a self-lubricating roller bearing clutch system that reduces chain slap and noise while enhancing chain stability for reliable performance on rugged trails
Crafted with forged aluminum links, a carbon fiber outer cage, and titanium hardware, this derailleur combines lightweight durability with high-end engineering to withstand the demands of aggressive off-road riding
The X-Horizon design maintains a consistent chain gap across all gears for smooth, precise shifting and eliminates ghost shifting, boosting rider confidence and gear accuracy
Innovative pulley technology with X-Sync 12-tooth upper pulleys and a wide/narrow tooth profile maximizes chain control, minimizes noise, and improves overall drivetrain efficiency, optimized exclusively for SRAM's 1x11 components.
