Hayduke started with a vision for the perfect hardtail. With the titanium version, we bring that same mindset to a timeless frame material. Designed around progressive frame geometry and built for versatility and longevity, 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 this generation, we've dialed in the geometry for a balanced and playful ride quality out on the trail, crafted up a lighter and longer lasting titanium tubing design, and included a host of braze-ons and new seatstay rack mounts 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 Ti is made from seamless, butted, cold-shaped 3/2.5 titanium—delivering an enduring and iconic hardtail mountain bike.
With a 120mm 29er fork, and clearance up to 29x2.6 or 27.5x3.0, the Hayduke can use your wheel size of choice to take you from the flow trail to the backcountry in one package
The versatile Portage dropout system was designed for riders to easily switch drivetrain types, hub widths, wheel sizes, and chainstay lengths. Set it up how you like, and hit the trail.

Esker Cycles - Built for the Back Country
We here at Esker enjoy long rides into the wild spaces and are proud to say our bikes are truly Built for the Backcountry. That means they are designed and built on three tenets:
Durability
We build our titanium hardtails from seamless, double-butted 3/2.5 Titanium for the utmost in durability.
This tubeset provides a greater strength to weight ratio than other Titanium frames on the market, engineered specifically for its application. Titanium is corrosion-proof, so you can ride through any weather, for life.
Geometry
With specific geometry to suit the riders needs for each different model, we have designed and developed a quick and responsive ride quality for the new Japhy. Utilizing size specific headtubes and shorter and steeper seat tubes we have given this bike a more playful trailbike feel that will make you want to throw it around the corners and pop off every little bump in the trail.
Ride Quality
Titanium is legendary for an almost mystically smooth, fatigue-reducing ride quality. The custom drawn, seamless, and butted tubeset is tuned to each size, which gives it more compliance and is lighter weight while also increasing torsional rigidity and overall strength.
