Doctahawk Frame

$1,900   CAD

Longer, lower, slacker, faster, stronger, slacker, etc etc, did we say slacker?

If you liked where the geometry of the Rootdown was headed but it wasn't enough, then the Doctahawk is for you.

Handbuilt in Canada with our custom-drawn tubes and featuring a 12 X 148 Boost rear end and stealth post routing, this is the most aggresive Chromag to date. Don't let the 62° head angle fool you though, the Doctahawk actually features the steepest seat tube angle in the line making sure you can get up to get down. Coupled with 180mm up front there's plenty of opportunity to hear "I can't believe they rode that on a hardtail!".

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.
