"Built to go fast and jump shit. This ain't no curb nibbler." - BF
Brian Foster is the ultimate trail boss; anyone who's been in the game long enough can tell you that. He wanted a frame that could flow through trails but still shred parks. A longer back end, 74° head tube angle and welded-on brake mounts make this the perfect trail frame. No joke.
