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.
