Although Sector 12 is designed to put you in the air, your tires don’t need to leave the ground unless you choose. Optional extremely difficult B-lines exist, which include rock drops and even a gap jump. Sector 12 showcases the GIANT granite boulders that are plentiful on the mountain.

      The only trail at GR that I've wanted to ride more than once. Still needs some adjustments, the speed required for some of the consecutive jumps varies wildly from dabbing brakes to last minute hammering.

      Downhill trails don't get much better than this. The opening half is fast and flowy with plenty of large table top jumps, perfect for riders looking to send their first big jumps. Rock gardens and tight berms keep things interesting all the way to the end. And for those who dare the final step down and gap jumps are features big enough to keep the best riders excited. 10/10

      We hope you've been enjoying Trailforks!
