Chromag Rootdown Custom Built Bike


The Rootdown is hands down Chromag's best selling bicycle. Built with custom-drawn tubes and featuring a 12x148mm Boost rear end and stealth post routing, this is the evolution of Chromag frame design in 29er form, compatible with tires up to 29" x 2.5 and 27.5+ up to 2.8 wheels. An agile ascender and a dominant descender that is ready for anything.

DISCLAIMER: This bike was custom built by us and the components have been specifically selected for this build. It is available in two colors because we can replace the black frame (on pictures) with a red frame in the same size which is in stock in our store.
