The SRAM Grip Shift is built on the idea of making shifting easier and more intuitive. The modern version of this shifter houses some of the most advanced and reliable mechanical shifting technology available. Weight:221g Durability and Control: The new robust internals make the shifting performance even more precise and extremely smooth when shifting between gears in all weather conditions. Rolling Thunder technology evenly spaces the load beneath the Grip Shift when rotating, meaning gear changes are crisp and smooth. Key Technologies Jaws: Once the Grip Shift shifter and grip interlock securely, forged aluminium clamps on either end reinforce the assembly by locking tightly to handlebar. Rolling Thunder: Three rows of ball bearings provide zero friction or play, reducing the force needed to shift and promoting long-term performance under all weather conditions. Speed Metal: Full metal indexing keeps shifting crisp and precise with Grip Shift. X-Actuation: Developed specifically for SRAM 1x, X-ACTUATION keeps shifting sharp and consistent across the entire cassette.
