Built with Chromag's custom-drawn tubes and featuring a 12x148mm boost rear end as well as stealth post routing, this is the evolution of Chromag frame design in 29er form. The Rootdown is compatible with tires up to 29x2.50 and 27.5+ up to 2.80 wheels. The Rootdown is an agile ascender and a dominant descender that is ready for anything.
The frame is made from quality 4130 chromoly steel tubing. Chromoly is an abbreviation for chromium-molybdenum indicating the materials that the steel is alloyed with. The added chromium helps increase the steels hardenability and also provide some corrosion resistance. The molybdenum helps to increase the toughness of the steel.
It has a high tensile strength but is also malleable, giving Chromag frames their notorious ride quality and feel. Chromoly is often used when more strength is required than that of mild carbon steel.
The Rootdown offers something for everyone from seasoned vets to first time riders. The reactivity of hardtails allows them to be great learning devices for everyone. Paired with its ability to run 27.5+ tires, you can truly ride this bike year round.
