The Rootdown is hands down Chromag's best selling bicycle.
Built with our 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.
4130 Chomoly
Almost all Chromag frames are 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 which is what gives our frames their notorious ride quality and feel. Chromoly is often used when more strength is required than that of mild carbon steel.
It falls under the AISI (American Iron & Steel Institute) 41XX designations which is where the “41” comes from. The “30” indicates it contains approximately 0.30% carbon by weight.
Chromoly is much stronger than traditional 1020 steel and it has a higher strength to weight ratio and high tensile strength, which means we can use less material and achieve a product that can withstand the abuse that riders love to throw at it.
