The GP series is an ideal answer to common wrist pain when cycling. The GP4, with its pure rubber compound and multiple hand - position options, offers an ergonomic way to relieve wrist pain. It has an easy - to - install clamping mechanism and ergonomics that are gentle on your back. Note, it's not for carbon handlebars. Say goodbye to sore wrists and numb fingers! When you ride, your hands bear much of your upper - body weight on the handlebars, which can pinch the ulnar nerve and cause numbness. The wing grip spreads pressure over a wider area, increasing support and preventing discomfort. If your wrist is bent for too long, it can compress nerves, tendons, and blood vessels, constricting the carpal tunnel and harming the median nerve. The wing design of our GP grips gives your hand more support and positions your wrist ergonomically, preventing numbness and pain. Ergon offers these grips in two sizes - Small and Large - for a personalized fit. For hand/glove sizes 6.5 to 8.5, choose Small; for 8.5 to 10.5, Large is usually better. The grip rubber is Made in Germany, meeting high - quality purity standards, TÜV - certified, and durable. It's developed without filler and uses medical - grade white oil as the only plasticizer. The UV - resistant compound is exclusive to Ergon. The GP Series clamping system is secure and easy to mount. Each grip is tightened with one bolt to prevent twisting. The cold - forged aluminum clamps are stronger. Grips with lightweight barends made of glass - fiber - composite and grippy rubber inlays offer extra hand positions for more comfort. Ergon's super - soft, UV - resistant rubber with a special surface texture provides a firm grip and maximum comfort, enhancing your riding pleasure.

Using your Ergon GP4-L cycling grips is a breeze. First, make sure your handlebars are clean and dry. If your bars are carbon, don't use these grips as they're not suitable. Then, place the grip on the handlebar and use the single - bolt clamping system to tighten it securely. This will stop the grip from twisting while you ride. When you're riding, try different hand positions on the grip and the wing design. They'll help distribute the pressure on your hands, so you won't feel numb or have sore wrists. If you have a larger hand (hand/glove size 8.5 - 10.5), the Large size is for you; for smaller hands (6.5 - 8.5), go for the Small size. To keep your grips in good shape, clean them regularly with a mild soap and water. Avoid using harsh chemicals as they can damage the rubber. Store them in a cool, dry place away from direct sunlight to prevent the UV - resistant rubber from degrading. Check the bolt on the clamping system every now and then to make sure it's still tight. And that's it - enjoy a more comfortable and pain - free ride with your Ergon grips!
