Well, I see now why you bikers like the spandex...Thanks for the info...I just figured a lot wore it because it looks “professional”...I was mistaken...Those are good reasons to wear it....
Some of my friends who wear brightly colored jerseys believe that it makes them more visible on the road. Given how much people dislike cyclists, I think it makes them good targets.;-)
BTW, I only ride my road bike (and mountain bike) at a local state park. No cars...and very few hikers.
