When SRAM began developing XX, they were looking to create the lightest, most precise and technically advanced components possible, and boy have they delivered! The XX Rear Derailleur is crafted from carbon, titanium and forged magnesium to ensure a ridiculously low weight, while still delivering the precision and durability SRAM is known for. Plus, it utilizes SRAM road technology that moves the derailleur in equal increments to prevent slop and provide lightning-crisp gear changes. What's more, the XX boasts sealed ceramic pulleys for slick shifting action and outstanding reliability.
