Ergon GP3 Evo Bio Kork Grips All Day on the Bar, Without the Aftermath Long days on a flat bar take a toll on your hands, wrists, and forearms - especially when your grip options are limited to one position. The GP3 Evo Bio Kork solves that with an ergonomic winged platform that supports the wrist in a straight, neutral position and three-finger bar ends that give you a second hand position whenever the primary gets old. The bar ends are fully rubberized for damping and adjust independently of the grip body, so you can dial angle without touching your grip setup. The cork and rubber compound body feels natural against bare skin and keeps hold through sweat and variable conditions. For riders who cover serious mileage on flat bars, these are worth every dollar.
