Get a grip! The XX1 Grip Shift features SRAM 1 x 11 X-Actuation for precise and dependable 11-speed performance. Developed specifically for SRAM XX1, X-Actuation keeps shifting sharp and consistent across the entire 10-42-tooth cassette. Speed Metal index shifting keeps shifting crisp and precise. Once the shifter and grip interlock securely, forged aluminum clamps on either end reinforce the assembly by locking tightly to the handlebar. Three rolls of ball bearings, which SRAM calls Rolling Thunder, provide zero friction or play, reducing the force needed to shift and promoting long-term performance under any weather conditions.
