Long, slack, and unapologetically aggressive, the Doc redefines what a 29er hardtail can do.
Handbuilt in Canada and paired with a 170mm fork, it’s the kind of bike that makes people say, “I can’t believe they rode that on a hardtail.”
A 4130 chromoly steel front triangle delivers Chromag’s signature ride feel, while 6066 aluminum chainstays and a forged aluminum rocker add stiffness, strength, and precise bearing integration.
