Lately whenever I ride trails with my mountain bike my left hand starts to hurt (sometimes my right one does the same thing, but not lately) This is usually after a few miles in to the ride and during a downhil (bumpy) part.
The part of my hand that hurts is around my ring and pinky fingers. These fingers start to hurt a lot near the knuckle and then my knuckle starts to hurt.
At first I thought I was using the wrong gloves. So I swithced from my fingerless PIs to my BMX Fox gloves. Same issue.
Then I thought it was the ammount of bumpage I get from riding on heavily rooted trails. I checked my tire pressure and my front fork and realized that they are on a very low setting. The tires are at 35psi, and the fork is very bouncable.
Whenever I ride my road bike and my BMX I have no problem with my hands. I have ridden my mountain bike for over a year now, and this issue only came about 50 miles ago (beginning of this seaseon), despite the bike having over 300 miles on it.
Does anyone know why my knuckle is hurting after a mountain bike ride?
Any thoughts and suggestions are welcomed.
