I've wanted to bike across country for a couple years now and being out of college, now have the time to dip work and ride. I am most likely going to do the TransAmerica route, for simplistic reasons. My intentions are to use my ride to raise money for Autism, a disorder affecting thousands of kids everyday.
Anyway, I am wondering if a mountain bike is okay or should I buy a road bike. I have a road bike now but its already been across the country (passed down to me) and is in pretty shabby conditions. I am used to mountain biking though, but my GT frame is an aluminum 3 pounder and it needs a lot of work. Great for trails, but I am guessing not too hot for the country roads.
So, any information on bikes, other gear and of course, tips for the Trans Am trail would be great. I live in Pittsburgh now, but am moving back to Cincinnati, Ohio in July and might plan to go to VA from there. Yes, I am a newbie, so don't poke fun!
