Hayduke started with a vision for the perfect hardtail. Designed around modern frame geometry, a versatile dropout system, and custom drawn tubing, Hayduke is a capable mountain bike built to be used as a single-speed, a singletrack machine, or a bikepacking rig. Since its creation, the story of this beloved hardtail has been one of local singletrack rides, stargazing overnighters, and worldwide exploration.
With the next generation, we've updated the geometry for a more playful and responsive character out on the trail, crafted up a lighter and stronger proprietary tubing design, and added a plethora of braze-ons to attach anything that you can dream up—all while staying true to the character of the bike to keep the soul of the Hayduke.
Hayduke's steel frame uses a custom drawn externally tapered, seamless, quadruple butted, heat treated 4130 cromoly tubeset that is specific to each frame size—making for a better quality frame while reducing weight and cost for the rider.
The versatile Portage dropout system was designed for riders to easily switch drivetrain types, hub widths, wheel sizes, chainstay lengths, and accept racks. Set it up how you like, and hit the trail.
“The Hayduke is superior for rugged bikepacking... I’m exploring new terrain every day and the Hayduke is the best tool for the job.”

“Hayduke is a steel hardtail with a trail bike attitude and impressive versatility.”

“Smooth singletrack, technical trail, bikepacking, and downhill riding, the Hayduke crushed it all.“
