Mountain biker here! Brand new to this sport, but not really. i got my first mountain bike 15 years ago when I was twelve. I hit the dirt at that young age and continued XC into my teens. The only problem was, I lived in a totally flat area! Now that I live in the hills, I am finding whole new challenges and I love it! Plus, the clipless pedals are giving me even more of a challenge (while I learn them)...
