Wing grips: help with numb hands
A common problem with travelling long distances is the high amount of pressure put on the sensitive ulnar nerve. This runs along the ball of the little finger, just below the surface of the skin. Too much stress on the outside of the hand causes numbing on the ring or pinky finger. One solution is to replace a conventional grip with a wing grip with palm rest, like what Ergon, SQlab or Contec have in their range. The contact area and thus the contact surface of the hand is increased, and pressure is better distributed as a result. If, on the other hand, pain occurs in your index and middle fingers or even your thumb, too much pressure on the exit of the carpal tunnel may be the cause. Your wrist is bent too much, which compresses the nerves. In particular, when you grow tired on longer rides, it becomes difficult to keep your hand in the ergonomically correct position. The wrist bends downwards, and the hand becomes numb. This results in carpal tunnel syndrome. Again, a wing grip can provide support and keep the wrist in the correct ergonomic position. Grips like the GS1 from Ergon are specially-designed for long distance mountain biking. For mountain bikers, it is also true that if the wing is too big, the off-road capability suffers. This is why there are different available wing sizes, which can be found on the Ergo Lock-On from 3min19sec or the GA3 from Ergon.
