A few year ago, I broke my neck riding (actually, falling) when three guys tried to rob me. Though it hurt like heck at the time, the injury still plagues me today. In fact, I find it difficult to ride with drop bars. Using them, I have to crouch lower than my stiff neck will allow. I can't curl my head up enough, for long, to see where I am going. So...
I tried different handlebars. The mustache bar is comfortable, but seems to make the bicycle feel twitchy. The effect is not awful, but noticeable. None the less, my
Motobecane Grand Jubilee is the vintage bicycle I ride the most.
However, when building up my last Junk Bike, which I call
Junker II, I learned something truly important to my riding comfort - bullhorns!
I fitted a pair of theme to my Specialized, installed some aero brake levers (nearly identical to the ones on your wife's bike), and voila - near perfect comfort, easy to reach brakes and very easily adjustable to find that sweet spot...
