More support with more comfort Why not combine the best? With the GA3, the winged grip has proven its genius to the All-Mountain world. The special thing about the GP1's off-road cousin is, he locks on tight with a lightweight inner clamp. The concept combines all the relief benefits of the wing and actively supports your wrist. Your freedom of movement and the accompanying bike control remains fully intact. Riding pleasure guaranteed! What exactly are the benefits of the wings on the grips? The longer a ride is, the harder it is for a rider to maintain the ergonomically correct hand position on the bike. As a result, riders often bend their wrists too much, stressing nerves and tendons and inhibiting blood circulation. Numbness and pain in your hands are often the undesirable consequences. The GA3 grip optimizes the hand position through the Miniwings and prevents over-bending in your wrist. What is the carpal tunnel? The carpal tunnel is an anatomic passage in your wrist for nerves and tendons running from the lower arm to the hand. If the wrist is bent too much the nerves become constricted, which often leads to pain and numbness. The GA3 with Miniwing is based on the well-established and proven design of the MTB-specific GA2 grips. The particular shape of the grips provides you with great comfort and grip, without compromising the freedom of movement. This allows you to have all the control you need to tackle the most demanding of trails with full confidence. As an ergonomically perfected expansion of the GA-series by Ergon, the primary purpose GA3 grips is to provide relief out in the trail. But, they're not only perfect for the MTB category, they are also ideal on fitness-oriented and urban bikes. The ergonomic winged-grip GA3 is available in five striking colors. Ergon grips don't just feel great, they look great, too!
