Trail tested, bikepacking proven—ride the Surly Karate Monkey!
Description |
The Surly Karate Monkey is a do-it-all steel hardtail that blurs the line between trail bike and bikepacking rig. Designed to run 29" or 27.5+ wheels, it’s incredibly adaptable whether you're sending singletrack, commuting gravel, or loading up for multi-day dirt adventures.
Built from Surly’s signature 4130 CroMoly steel, the Karate Monkey features modern trail geometry, massive tire clearance, and mounts for everything. Run it rigid or with a suspension fork, 1x or 2x drivetrain, tubeless or tubes—the setup is yours to define.
Finished in the eye-catching Snow Mold White, this frame is equal parts gritty and classy. At Dismount, we’re proud to offer Surly bikes across Canada—and the Karate Monkey is one of our most popular.
