Is there anything wrong with riding my old road bike on trails? It has 27X1 1/4" tires so it's not bad, but I was wondering if that's some kind of no-no, as in it causes more trail wear or something? I don't care if I look like a Fred, but I don't want to be ignorant.
Also, the reason I am thinking of it is it may be icy on the roads this weekend. Would it be any better on a trail? Am I likely to bust my rear-end?
