I think I've only done one post on here but I'm on here almost every day getting some great tips and advice which I've used. I started biking again over a year ago. I was riding a Raleigh Passage 3.0 hybrid and did some charity rides of 30-50miles and a metric century when I decided I needed something a bit lighter and got a Trek 7.5fx wsd in December. I love it, rode it all winter and use it on MD's paved roads doing about 70 miles a week. In Sept. because of my turning 50 this year(and having to prove a point) my sister and I have decided to do the C&O canal over a 4 day period. I'm not sure whether to take the Trek and put different tires on it for the trail which the LBS assures me can be done(it now has 700x32c) or to go back to the Raleigh for this ride which seems to be more made for the trail(700x38 if I remember right). I know a few of you did the trail last fall - does anyone have any ideas or suggestions for which bike to use? If I'm going to switch back to the Raleigh for this ride I'll probably need to start riding it again in a month or two to get ready.
