The Rootdown is hands down our 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.

The Rootdown Series VI
There isn't much a Rootdown hasn't done. Its made for all around hardtail shredding in all kinds of trail conditions. Its a versatile All-Mountain 29er hardtail featuring premium materials, detailed construction, and progressive geometry. The Rootdown is a versitle trail bike eager to keep going mile after mile. With confidence inspiring geometry it is both surefooted and involving. It is our best selling hardtail by far with a cult following. The Series VI has been updated with post mount brake tabs, threaded BB and E.D. tube coating.
4130
The Rootdown 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 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.
Electrophoretic Deposition
ED (Electrophoretic Deposition) coating is the process of applying a thin layer of coating to all surfaces of a part, both inside and out. Our ED coating is applied by fully submerging the frame in a liquid, to which, an electric field is applied (a bit like anodising). Not only does this completely envelop the frame inside and out, but it provides an incredibly even layer of protection. This gives our frames great corrosion protection as the inside of all tubes are also coated. The ED coat also acts as a great primer for the paint to adhere to.
