These Renthal grips feature their most advanced compound to date. The grips are super-tacky with a soft, grippy feel combined with a highly durable base. The base material is reinforced with millions of randomly aligned DuPont™ Kevlar® particles. As the grip is used, more particles are exposed, so the percentage at the grip surface increases. Special technology insures maximum retention of tackiness under exposure to sunlight and weather. Developed and tested using the input and assistance of top factory race teams from Europe and North America. These grips are simply revolutionary, with the softest material produced in a grip which also lasts at least three times longer than standard soft materials. Full diamond pattern in natural color. Sizing: Standard: 115 mm (4.5") in length, 29 mm in diameter for use on most bikes.
