I'm having problems with my hands and arms getting numb after about an hour of road riding, especially my right hand. I change up hand positions but it doesn't help. Last time I rode it was so bad I couldn't work the buttons on my cycle computer. I don't have that problem on my mountain bike. Seems like I saw an article a few months ago on seat and handlebar positioning to fix this problem. Did anyone else see the article or have any suggestions about how I can fix this?
