  • "I want a bike that is lawless. I want to be able to descend anything I find myself above but I want to get up there with minimum of fuss and maximum speed, which is why I want a 29er. Too many people discredit 29ers as being only for old guys and cross-country racers, but bikes like the Rootdown defy small-minded definition. I’ve tried my hand at all types of mountain biking but after years of searching I realized I just like being out on the trails and that specific categorization is a waste of time. I just want to fly through the woods, feel the loam flick up on my shins, and never have to worry about wiping the grin off my face."

  • Big wheels, all mountain

    Following the success of our Surface frame, we've taken the same agile geometry and modern features to production to create the Rootdown. All the details are included here. It features a 44-millimeter head tube to accommodate tapered steerer forks and a 31.6-millimeter seat tube for more dropper post options. Our own original ideas like the "Yokel" joint and ISCG tab system are also included. Made with custom drawn tubes to our specifications, the Rootdown features added fork clearance at the down tube and extra stand over clearance at the top tube.
