On the other hand, our true gravel backroads designed for vehicle traffic are often MTB, only, and even then, the MTB makes a difference. Since our woods are basically built on a huge pile of sand, some of our backroads that are not graveled over are fat bike country, only. The deep sand just swallows anything else. In fact, a lot of us, up here, use fat bikes for all of our MTB riding. We use fat bikes all year long.
