I've read an article about the causes/solutions to neck pain while cycling. I know that more aggressive positions are more likely to cause neck pain, and handlebar height and excessive reach are the two main things to check when you are having neck pain...

I just got a new to me road bike and it has aero bars. I love riding with the aero bars, but I don't really understand how my head should be positioned? So that I can see ahead, although that strains my neck? Or so my neck is comfortable, but I can't see very far ahead? Or maybe alternate between the two? What do you do?
