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, chainstay lengths, and accept racks. Set it up how you like, and hit the trail.
