Next time you ride your bike, notice how you hold your handlebar. Is your hand wrapped so tightly your knuckles are white? Is your wrist bent?
If so, it's probably time to consider good body mechanics. Try keeping hands, wrists, and forearms level and straight. Avoid bending the wrist, which increases pressure on sensitive tissue.
Awkward handlebar positions can cause hand fatigue and pain. They stress the ulnar and median nerves, both major structures that run through the arm into the hands.
Compression or squeezing of the ulner nerve, for example, can lead to neuropathy, also called handlebar palsey. Carpal tunnel syndrome is a painful condition involving compression of the median nerve where it passes through the wrist.
Numbness, tingling, or weakened grip are a few symptoms of irritated nerves in overstressed hands.
Head off potential problems with proper body mechanics, wrapping your handlebar with shock absorbent tape or grips, and wearing supportive bike gloves.
