Otso’s Warakin is their titanium all road and gravel bike with versatility in mind. This bike can be built to suit your needs from bikepacking to gravel racing and has the ability to tackle any road, all with a light and lively feel thanks to the 3Al/2.5V B338 grade 9 titanium. It’s durable, lightweight, corrosion-resistant, and timeless. Keep this bike for decades to come.
Today Otso announced updates to this frame, with bigger tire clearances and updated geometry. It’ll fit 29″ x 2.1″ for 4×4 jeep roads, or 650b x 50mm pleasant, loamy forest roads, or even 700c x 35mm for your next gravel race or ride. As you swap out wheel and tire sizes, the Tuning Chip rear dropout system allows you to tune the geometry to lengthen or shorten the wheelbase by up to 20mm and raise or lower the bottom bracket by up to 4mm.
The Warakin Ti is initially available as a frameset and as a complete build. The frameset ($2,800) includes a frame, fork, and Wolf Tooth accents. The complete build is based on the Shimano GRX drivetrain and begins at $3,950.
