Our ergonomically designed BioLogic Arx grips support the palm of your hand and position your wrists to let you relax more during rides, resulting in less fatigue and more control when you need it. The grips lock into position on the handlebar and a triple density design puts a soft compound rubber just where you need it. Stashed inside the grip is a patented T-Tool–an integrated 4/5/6 mm hex key tool–so it’s always there when you need it.
