But another key concern you may not have heard of is handlebar palsy, a problem that's particularly serious in mountain bikers.
When you grip the handle bars, the repeated shocks that occur when you bounce over terrain can cause this so-called handlebar palsy.
Handlebar palsy has several symptoms: numbness, tingling, pain in the arms and wrist, even the little finger.
