What is the proper road bike posture (generally speaking)? I've been having a little back, neck, and wrist pain (nothing major) while riding. I was having numbness in my left hand while riding, but I went back to my LBS and he did some slight adjustments - moved the handlebars down to relieve pressure on the hands and moved the seat back just a bit. The bike in my avatar is the one I'm referring to. Any other suggestions?
p.s. My girlfriend and I are bad about not stretching before we ride. Does that help minimize back and neck pain while riding? Thanks again!
