Running a 1x twist shift setup? The Ergon GA3 Single Twist Shift Grips are among the few ergonomic grips designed specifically for it. The right grip is shortened to accommodate the shifter while the left runs full length, and a mini-wing gives you meaningful palm support without getting in the way of your shifting motion. Made from a super soft, UV-stable rubber compound, the varied thickness design damps vibration well and reduces hand fatigue on longer trail days — a small upgrade that makes a real difference if you've been stuck running plain cylindrical grips with your twist shifter.
