XX1 is SRAM’s newest drive train group, designed to simplify the traditional mountain bike drivetrain and make it more efficient. The XX1 X-Horizon rear derailleur features a horizontal parallelogram design that eliminates vertical movement, creating a derailleur that shifts faster, requires less force to shift, and eliminates ghost shifting. The XX1 X-Horizon rear derailleur also features a roller bearing clutch that helps minimize chain slap and bounce, and makes rear wheel changes a breeze.
