I have always ridden a Mountain Bike up until a month ago when I bought a road bike, have been spending more time on that than the MTB now, much prefer the MTB riding and racing but heaps easier to get out on the roadie and dont have to scrub it after a ride, feel like I am getting more out of my training on the roadie than I do on the MTB too and head out to some fairly interesting places on the Road Bike, Great Ocean Road the Dandenongs etc. so still a nice ride, but yeah nothing beats a good bit of singletrack on the MTB!
