SRAM Xx1 2.1 Rear Derailleur

SRAM is one of the largest bicycle component manufacturers who are known for producing quality components and, over the last decade, the brand has pursued an aggressive approach to drivetrain innovation. The XX1 2. 1 is the latest example of SRAM's innovation, and the lastest iteration of SRAM's XX1 X-Horizon Derailleur. The design is based on a horizontal parallelogram that moves the body on a horizontal plane rather than up and down. By limiting the movement of the derailleur, ghost shifting becomes a non-issue. Additionally, there is a small offset between the upper and lower pulleys. No, they aren't misaligned; they are designed specifically to provide a constant chain gap throughout every one of the rear gear ratios. This means smooth, consistent shifting whether you are shifting up or down. The body is fabricated from carbon fiber to maximize strength to weight.

• 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.
