The world class downhill grip is now even better! By working together with top professionals like Rémy Métailler and Vali Höll, the GD1 has evolved to provide even more comfort and control in demanding terrain. The GD1 Evo features more damping, better control, and enhanced comfort for more riding fun. Less gripping power is required due to its conical shape, super soft thumb zone and new inner stop design. The GD1 Evo is twist-proof on carbon handlebars and available in two diameters.
