I have ridden at North Star a handfull of times. The only thig that I cant figure out is why my hands go numb after about 6 hrs. of riding. I have a pair of ODI Oury lock on grips on my bike and the stock Specilaized DH bars and every day my hands are dead? I have fairly large hands but Im not sure what grip to get? Any suggestions? Also Anyone have any oppinion on good Goggles?
