Doctahawk 27.5+"/29"
Powerful climbing, aggressive descending. That's what the Doc ordered!
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!".

Chromoly Tubing
Making modern chromoly frames is challenging when most of the tubes available on the market are from an era of mountain biking long past. After several years of frame production we reached the point where we could design and produce our own custom tubing for the majority of our frame tubes. This contributes to the unique look of many of our frames but more importantly allows us to configure our bikes exactly as we want for each design.
Dropouts
As 12mm through axles have proven to be solid, reliable and convenient, we have committed most of our models to utilize this format. Our 12mm dropouts are accurate and tough and feature a removable derailleur hanger with a sturdy interface for strength and reliability. All 2019 models (excluding Monk and Nice Dreams) will follow the 148mm boost spacing.
Head Tube Badge
Bikes are special. The headtube badge is the finishing touch so we’ve always made a point of taking the time to do something interesting with it. Our headtube badges have changed over the years and are an indication of the time each bike was made. Whether it’s a cast bronze, or polished stainless steel, water cut aluminum or a 3D CNC carving, each one represents our commitment to detail.
Yokel
Our ‘Yokel’ design is a small machined junction on the chainstay that helps accommodate both tire clearance and chainring clearance. Our first versions were huge CNC yokes that bridged the entire front end of the chainstays. Over time we refined this to minimize weight by arranging our chainstay layout asymmetrically and reducing the yoke to a minimal size. It’s one of our most unique frame features and has been copied by other frame makers.
