Chiba BioXCell Gloves
The first question when buying gloves should be whether your hands fall asleep, as 80% of all cyclists have problems here. In this case a BioXCell glove from Chiba can help:
The BioXCell upholstery consists of an ergonomic 2-stage special gel cushion that lies in the palm area over the ulnar nerve. The ulnar nerve is optimally protected by the almost 0.8 cm thick ergonomic padding. At the same time, the pressure points of the handlebars on the hand are changed and the pressure on the middle of the hand or carpal tunnel is greatly reduced. With BioXCell from Chiba, numbness in the hands is a thing of the past in 80% of cases. If there are still problems with the hands despite BioXCell, the handlebars and grip position must be changed in addition to the gloves. Please also make sure that the glove is not too big, as in this case the ergonomic BioXCell padding is not positioned correctly (it is too far out) and does not work properly.
WHY DO HANDS FALL ASLEEP?
The hand is traversed by two central nerve tracts, the ulnar nerve and the carpal nerve. When carpaltunel syndrome is used colloquially, several problems are usually lumped together. As can be seen in the drawing, the ulnar nerve leads to the outer ball of the hand to the little and ring fingers. He is not so sensitive to bending his hand, but is negative to pressure in the ball area. Especially with racing bike handlebars, the pressure on the outer palm and thus on the ulnar nerve is maximum. This pressure leads to numbness and weaknesses in the hand muscles.
A second source of problems is the central nerve (median nerve). It runs through a narrow tunnel in the wrist (carpal tunnel). Pressure and bending the hand lead to the well-known carpal tunnel syndrome. Carpal tunnel syndrome causes numbness and weaknesses in the thumb, middle and forefinger. In severe cases, the numbness disappears long after the bike tour or gets worse overnight, as the tissue of the hand tends to swell slightly at night.
In summary one can say:
90% of the pain and numbness in the hands are due to the following reasons:
1. Pressure on the ulnar nerve that supplies the small and ulnar part of the ring finger.
2. Pressure on the carpal tunnel (supplies the remaining fingers)
3. Unnatural bent position of the hand in the wrist.
4. Shocks and vibrations that irritate tendons and nerves.
