Japhy was born out of the desire to ride everything from the backyard to the backcountry.
The new titanium version brings that same intention in a timeless titanium package. Japhy is the hardtail you reach for no matter what the ride ahead promises.
Japhy is designed and built to satisfy your adventurous side, and is equally at home on your favorite flow trail or an overnight epic.
Japhy Ti is designed around progressive frame geometry and custom titanium tubing for a playful and responsive character, and an unmatched ride quality out on the trail.
Japhy Ti is made from seamless, butted, cold-shaped 3/2.5 titanium—delivering an enduring and iconic hardtail mountain bike.
With a 120mm fork and clearance of 29x2.4 in the middle dropout position and up to 29x2.8 in the rearward position, Japhy is ready to take on everything from backyard flow trails to backcountry singletrack.
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.
