Ok...so I need some help. My wife is a mtb. newb.. Trying to explain even basic things to her can be a struggle at times. For both of us. Example.... I was trying to explain the difference between a XC race bike and a trailbike to her just now. Her reply was, "don't they race on trails?" : You see my delema. Anyway, I was wondering if their is a website that might have a glossary of mountain bike terms that I could direct her to? She is a quick learner and I do my best ot explain things to her, but quite honestly, I'm not the best teacher. (should have seen us when I tried to teach her to snowboard.) Any suggestions.
