SRAM XX1 2.1 Rear Derailleur
Item Description
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. XX1 2. 1's horizontal parallelogram is the same design that set XX1 2. 0 apart from its competitors. Unlike a typical derailleur, the X-Horizon derailleur knuckle only moves side-to-side -- not up-and-down. This limits the movement to the horizontal axis, making ghost shifting nonexistent. Looking at the derailleur pulley wheels, you'll notice the offset of the upper pulley. Unusual in design, the upper pulley provides a constant chain gap through all of the gear ratios. Through the combined efforts of the X-sync chainring, pulley wheels, and a Roller Bearing Clutch, a chain guide isn't needed with XX1. Your chain is tensioned with the derailleur and locked in place with the pulleys and chainring. Also, combining the Roller Bearing Clutch and parallelogram design means that you'll never get chain slap, so your chainstay won't look marmot-gnawed. The derailleur is also made to withstand repeated hits while you're navigating through a rock garden in order to eliminate the chance of throwing the chain. We'd be remiss if we didn't sing the praises of the XX1 2. 1's Cage Lock technology. It locks in t...

About Us
We get people who get outside — plain and simple. Backcountry began in 1996 with two childhood friends and a stack of avalanche beacons in an apartment in Park City, Utah. Our roots were humble, but our vision was clear: to provide the best outdoor gear to connect people with their passions. At the dawn of e-commerce, we set the precedent that gear should be accessible from anywhere by anyone.
Today, we offer a broad selection of gear from premium outdoor brands, and we back that gear with lightning-fast shipping and guaranteed returns. Over two decades later, we still call the trails of the Wasatch Mountains in Park City home. And from the West to the East, from mountains to oceans, wherever you are in nature, so are we.
