Available NOW:   The Gnarzan is not your dad's mountain bike.  It's a thoroughly modern hardtail made for getting radical. Nimble enough for everyday riding and aggressive enough for a day at the bike park. With slack geometry and 27.5 x 2.8 /29 x 2.4 tire clearance you can tune your ride to dish out the right level of speed vs. gnar depending on how you feel like riding that day: 29 x 2.4" for slicing through the single track, or up to 27.5 x 2.8" for velcro grip and seeking out the steep grades & big drops.  The frame features a sturdy 6061 frame, Boost 148x12 technology, ISCG-05 mounts, dropper post routing, and an old-school english threaded bottom bracket (as well as no pivot points, bushings, or bearings) to keep the just-get-on-and-shred-gnar ride level real.
