The seemingly magical properties of silicone grips have made them popular items in endurance racing circles, and you're able to thank ESI for starting the trend. With the Racer's Edge Grips, ESI has brought that smooth ride and all conditions control to those of us who prefer thinner grips. ESI's grips are built from silicone for a host of reasons. Chief among them is the vibration damping that silicone provides. Basically, these are much more effective than a standard grip at canceling out high frequency vibrations, which ultimately leads to numbness and pain in the hands. It's especially noticeable during long rides, but the benefits will be apparent every time that you hop on your bike. Silicone is grippy stuff, which is good news, because that grip works in both directions. As a result, the grips are secured not only to your hands, but to your handlebars as well. In fact, when installed per the instructions, these grips stick firmly to handlebars, even in the rain. And naturally, they provide a solid hold for your hands, regardless of sweat or dirt. Better yet, because silicone has memory, these grips will break in to the shape of your hand, providing a custom fit that gets better the more that you ride them. These grips are offset, which means that they're slightly thicker on one side than the other. So, when installing them, make sure that you have the thicker end facing your palms, and the thinner end underneath your fingers. This will ensure maximum vibration damping, while still providing a direct steering feel. The Racer's Edge grips are fairly thin, and work well for riders with smaller hands, or those that simply prefer thinner grips. Riders with larger hands, or those who prefer thicker grips, will be better served by the ESI Chunky grip. The ESI Racer's Edge Grips are available in one size and in the colors Black, Blue, Green, Red, and White. Please note that we advise referring to the included instructions for correct installation.
