      I travel the land far and wide for gems like this. What a beautifully crafted large freeride trail! I really appreciate the way each feature complements the next, setting you up with plenty of speed and not having to reach to get to the landings! They’re big and fully gapped, but they are a well designed system of hits that work perfectly!

      We hope you've been enjoying Trailforks!
