In 2016 Chromag updated the Rootdown frame with a combination of longer top tube, shorter chain stay, slacker head angle, steeper seat tube and lower BB. It was a significant progression of the all mountain hardtail. The new 2017 version continues that legacy further with the additional clearance needed for 27.5 Plus tire compatibility.

Built with custom-drawn tubes and featuring a 12 X 148 Boost rear end and stealth post routing, this is the evolution of Chromag frame design in 29er form compatible to 27.5+. An agile ascender and a dominant descender that is ready for anything.
