The GE1 Evo Factory Grip was developed for the pros on Yeti's highly successful EWS squad who prefer a more traditional grip run on wider riser bars. The GE1 Evo is a refinement of the GE1 fueled by the feedback collected from its sponsored riders. It actively corrects your riding position down rough descents by rotating the grip area towards the steering axis by 8-percent. This positions the elbows up and in the attack position.Compared to the standard GE1, the grip's tread is even more aggressive and the GravityControl Rubber compound is softer providing optimal control without a death grip. The forged inner clamp locks the grips securely to the bars and is carbon approved. We love lock-on style grips since they are easy to install and are ready to ride right away. The integrated grip end is connected to the inner core for a softcore end that's comfortable in your hands even while hanging on to the ends of the bar. Careful attention was placed on pressure reduction on the ulnar nerve helping to reduce hand numbness.The Ergon GE1 Evo Grips come in the colors: Frozen Orange and Black, and in two diameters, Regular (32mm) and Slim (30mm).
