This past Christmas I went from a comfort bike to a road bike, complete with drop bars (Trek Pilot). The transistion was fine for about a month, then a funny problem developed. One day after riding 40 miles, I had my first flat. It was on the rear. I took the wheel off, changed the tube and was back on the road. I noticed that while changing the flat, my left hand seemed weak. On the way home, it was difficult to shift gears with my left hand.
Now, almost a month later, I find that after riding, my left hand is weak. I rode 25 miles today, and as I type this, my hand is weak. It feels weak from the elbow to the hand. It will be ok in a few days, but will be back after I ride.
I know you are supposed to change positions while riding. I sometimes hold on to the tops, then hoods, then drops. Sometimes I ride a few minutes with my left hand free.
I am wondering if I have damanged a nerve or something. Maybe carpal tunnel? I do not have any pain, just weakness in my left hand. Incidentally, I am left handed. Thanks.
