I'm fighting this problem right now. I never had neck problems when I was younger, but since I was about 25 I've been having neck pain on a road bike. I've been wondering if it's from a past motorcycle wreck neck injury. I don't have as much problem on a group ride when I'm keeping an eye on the bike in front of me rather than a solo ride where I'm looking farther down the road.

I bought some Oakley glasses to replace my Ray Bans thinking it was lower top of the frame and this has helped a little but hasn't solved it. My bars are about 6cm lower than my saddle so I'm thinking of changing my 7° stem for 17° stem to raise me up but I don't want it feel to like a cruiser but I may have no choice.

Stretching my neck before a ride helps during the early part of the ride, but later on it comes back. The pain is so bad I can't even stretch while I'm riding. I've got to figure something out or may have to go back to sitting on the couch
