Big wheels with big travel equals big fun. Welcome to Trek's Rumblefish I. It's got 120/110mm of travel, making this a fully capable trail bike with all the monster-truck benefits of big wheels. But the real deal comes in the form of a tight wheelbase along with a well-proven G2 29er geometry. Fox steps it up, too, with a custom fork to make steering and overall handling neutral while still being snappy, quick and playful. And play it does with a Fox DRCV-equipped shock out back and stiff Bontrager Rhythm wheels. The ABP keeps the rear end active while braking and the E2 head tube stiffens up the front end. A 10-speed SLX drivetrain and Avid Elixir discs round out the specs... get ready to rumble.
