Do you use a mtnbike or a road bike to tour, and why ?
I have toured for years on a mtn bike and always seem to find people who swear by road bikes.
I find the upright position more comfortable, the ride smoother, the low gears a blessing and the ability to hit the trails after dinner a nice change, I also would think that the fatter tires would help provide stability. Oh ya (knock on wood) there is also less risk of a flat with a mtn bike.
Let the debate begin.
