I'm currently owning a French Sunn mountain-bike, and one of the reasons to why I bought a mountain-bike and not a regular racer is because I once believed that you couldn't ride with a road-bike in the forest. I thought that the mountain-bike was more all-around. Now, I've been proven wrong!
Martyn Ashton is the rider in the video and he's a mountain-bike rider, but he's now found a Pinarello Dogma 2 which is the road-bike that won the 2012 edition of Tour de France. The bike is handmade in Italy and you have to pay $16,000 to get one.
