"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."

Specs

Big wheels, all mountain

A combination of longer top tube, shorter chain stay, slacker head angle, steeper seat tube and lower BB, continues the progression of all mountain hardtail. Stealth routing for dropper posts is standard as is full housing. Build with our custom-drawn tubes and featuring a 12 x148 Boost rear end, this is the evolution of Chromag frame design in 29er form. It's a stable ascender and a dominant descender.

Head tube badges

Bikes are special. The headtube badge is the finishing touch so we’ve always made a point of taking the time to do something interesting with it. Our headtube badges have changed over the years and are an indication of the time each bike was made. Whether it’s a cast bronze, or polished stainless steel, water cut aluminum or a 3D CNC carving, each one represents our commitment to detail.

Yokel

Our ‘Yokel’ design is a small machined junction on the chainstay that helps accommodate both tire clearance and chainring clearance. Our first versions were huge CNC yokes that bridged the entire front end of the chainstays. Over time we refined this to minimize weight by arranging our chainstay layout asymmetrically and reducing the yoke to a minimal size. It’s one of our most unique frame features and has been copied by other frame makers.

Tubing

Making modern chromoly frames is challenging when most of the tubes available on the market are from an era of mountain biking long past. After several years of frame production we reached the point where we could design and produce our own custom tubing for the majority of our frame tubes. This contributes to the unique look of many of our frames but more importantly allows us to configure our bikes exactly as we want for each design.
