Always ready to roll into the unknown at a moments notice. Loaded for the long haul or light and nimble singlespeed missions, this is the bike for your adventure rides.

What's the only thing that could be better than the original? A titanium version of course!

Staying true to the versatility you have come to know and the durability you have come to depend on, Hayduke can truly do it all and get you way out into the backcountry, and back again on every ride.  

With a wide range of sizes, size-specific headtube lengths, and optimized reach lengths, the Esker Hayduke provides a more accurate fit and maximizes your adventure potential

All Hayduke frames have external cable routing, threaded bottom brackets, and 44mm head tubes for durability and ease of maintenance. The Hayduke also comes with 13 attachment points for adventure accessories, and threaded rack mounts built into the frame. Whe you are far away from civilization, you will have one less think to worry about.

Hayduke Ti is made from seamless, butted, and cold-shaped 3/2.5 titanium - delivering an enduring and comfortable bikepacking hardtail mountain bike.

Optimized for a 120mm suspension fork, the frame has ample tire clearance, fitting up to 2.8" tires.

The versatile Portage Dropout System is now Universal Derailleur Hanger (UDH) Compatible. The system was designed to switch easily between drivetrain types, hub widths, wheel sizes, and chainstay lengths. Set it up how you like, and hit the trail.
