Using the latest in grip technology and molding techniques, ProTaper's Clamp-On Grip System offers the comfort and control of traditional grips with the added advantage of quick, effortless installation. The design eliminates the need for glue and tie-wire, yet ensures durable, slip-free performance. The super-slim clutch-side Windowed Core not only minimizes the outer grip diameter, but also delivers critical relief areas for the palm and fingertips. The result is increased impact and vibration damping over competing solid-core designs, leading to improved rider comfort and control. The grip surface utilizes an extra-supple, tacky compound that is seamlessly molded to the inner core. This provides maximum comfort and traction while alleviating palm abrasions and blistering. A firmer compound is used in the flange and endcap areas to resist crash damage and reduce wear. Easy on, easy off - no messy glue or safety wire needed.
