It is designed and built to satisfy your adventurous side, and is equally at home on your favorite flow trail or an overnight epic. Japhy is the hardtail you reach for no matter what the ride ahead promises.
Taking what we learned with Hayduke, Japhy is designed around modern frame geometry and custom steel tubing for a playful and responsive character out on the trail.
With a 120mm fork and clearance up to 29x2.8, Japhy is ready to take on everything from backyard flow trails to backcountry singletrack.
Japhy 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, and chainstay lengths. Set it up how you like, and hit the trail.
"The Japhy really comes alive on rough trails and chunky roads. While zipping along at speed, the Japhy skims effortlessly through rock gardens, roots, and rutted-out trails."

"Japhy is scrappy and is willing to claw its way through just about anything...The Japhy is a veritable ally for whatever you can throw at it."
- The Radavist
"It will pick up speed well, and it will shred, and it doesn't feel heavy going uphills... This bike is for someone that wants a really nice ride feel. It rides real comfortable."
