i HAVE THE SAME PROBLEM. IT SEEMS IT IS PART OF RIDING. MY NUMBNESS STARTED WHEN I GOT A ROAD BIKE, TREK 2200 AFTER RIDING MY JAMUS HYBRID FOR ALMOST A YEAR AND A HALF. I ADDED MORE TAPE TO HANDLEBAR, GOT NEW GLOVES AND TRIED MOVING HAND MANY DIFFERENT POSITIONS. NUMBNESS CONTINUES AFTER RIDING. MY CONCLUSION IS I AM LEANING FORWARD TOO HARD ON HANDLEBAR SINCE THAT POSITION IS DIFFERENT FROM MY RIDING TECHNIQUE ON A HYBRID.
SORRY I CAN'T GIVE YOU ANY FIX UP ADVICE BUT I HAVE A LOT OF EMPATHY
