Abstract

Abstract An improved grip for encircling the hand contact portion of a shaft, lever, or steering device for hand powered and hand guided equipment is made from a reversible thermoplastic rubber that is designed for use without vulcanization. The improved grip finds application whenever it is desirable that the hand grip be securely grasped and held, and especially when impact of a ball with a club or racquet is with sufficient force that it injures the hand. It is particularly useful in tape form for bicycles and motorcycles.
