Trail riding is different, but the principles can be successfully applied to road riding. I don't think a road bike suffers from as many limitations as people perceive. Much of my riding is on roads with sections that would give the Paris-Roubaix a run for it's money, but I have no hesitation riding 23c slick tires on all my bikes because I use technique to make up the difference. A bmx and mountain bike background has done a lot for the 'riding light' aspect. I've even been known to ride a road bike on single track and bmx trails (FUN!). It can be done.
