Hi all. I will be embarking on my first ride across the country on June 1st of 2008. I won't lie. I'm a definite newbie at the touring side of biking, but i've been riding most of my life. I currently own a Giant Iguana Mountain bike with pretty much everything stock accept slick tires and custom handlebars so I can adjust height for my bad back. I'm 25 (go figure, I'm this young and I have a bad back) and I'm really stoked for this trip.
One thing I am having a hard time concluding is whether or not I should use my current bike, which I do like and is confortable for me, or if I should get a road bike which seems to be a little more practical as far as speed, weight, etc. I went to my LBS and the person who has been helping me reccomended I get the Fugi Cross Pro. It wieghts a meesly 17.5 lbs and I took it for a quick spin today and it seemed like a pretty nice bike. Next week I plan on taking it out for 30 or 40 miles to give it a real test drive. It has a thinner mountain bike type tire on it with the larger wheel and will set me back about $1100.
I guess what I'm asking is, what are the advantages and disadvantages of riding a mountain bike vs a road bike? I will be taking the bikecentennial route across the states from West to East Coast. I'll be carrying a B.O.B Trailer behind me with possible panniers on the front of the bike. Any suggestions on whether i should take the trip on my current bike or go for the fuji? If not the fuji than what would you reccomend around the same price? I'm obviously a little lost as far as what exactly is going to get the job done the best, but I'm determined to go on this trip no matter what. Hope you can help!
