We have three local bike shops. I'm 60 (but behind my eyes I'm still 30) and have been looking at road bikes recently. No one has yet batted an eye. I don't think I really want a drop bar bike anymore though after trying a few flat bar road bikes but a couple of the shops kept making the point that we all know, more hand positions with drop bars. Anyone who makes a comment that people of a certain age should only do X are not people of a certain age.
