Build This Bike

For 2019, the Rootdown has been updated with a combination of longer top tube, shorter chain stay, slacker head angle, steeper seat tube, and a lower bottom bracket height. This is significant progression of the all mountain hardtail. 

The Rootdown can best be described as a hardtail that doesn't think it's a hardtail. It's a hardtail that will make you want to ride things that you'd normally ride on your big plush enduro bike with gobs of rear suspension travel. An agile ascender and a dominant descender that's ready for anything.

It's a versatile bike that can be built with either 27.5" or 29" wheels, with tire clearance up to 3.0" and 2.5" respectively. It is designed around a 160mm travel fork, but can accomodate 150mm and 170mm for those who want to go up or down in travel. The frame is constructed form a custom chromoly steel tubeset. The old adage "steel is real" still rings true today with the Rootdown. It's still a commonly used material for hardtail mountain bikes for several reasons, including excellent vibration absorption, and great strength to weight ratio. Chromag's "Yokel" design features a small machined junction towards the front of the chainstay that allow for ample tire and chainring clearance. At the other end of the rear triangle, Chromag has opted for Boost 12x148mm dropout spacing, which aids in providing a super short 16.3" chainstay length. Partner that with a 12.6" BB height, a 64° head angle and a 76° seat angle, and you've got a recipe for a wicked trail-ripping hardtail. 

The frame does not include a seatpost clamp, so we recommend purchasing one if needed.
