GRF1 grips are MTB grips designed for gravity disciplines by the world's best riders. Ergon created these grips in collaboration with Tahnée Seagrave and her Canyon FMD Racing teammates. This model offers a specific grip texture at the top. At the bottom, you'll find a new grip zone for maximum control and dampening in the most demanding passages. High-quality German-made rubber with TÜV certificate is raised in the sleeve area. So your hands won't slide down from the grip. With the GFR1, you'll be in control of your ride, with maximum precision. Name:GFR1 Black Use:MTB, Freeeride, Gravity Material:Factory Custom Rubber Sleeve:ColdForged Aluminum / CNC Machined
