Our original all-road bike. The Warakin Stainless was one of the first bikes we built when we created Otso in 2016. It's been such a hit over the years that we haven't changed the geometry one bit. Stainless steel has a ride quality that is familiar, yet surprising—smooth like steel, lively like titanium. The Warakin Stainless is ready for your next century, three-day bikepacking trip, or afternoon group ride.


The supple-yet-lively ride quality of steel with the corrosion resistance of titanium. Stainless steel is lighter than you think, loads of fun, and ready for your next full day on the saddle.



700c? Check! 650b? Double check! 29er? Triple check! Warakin Stainless has massive tire clearance.


The Tuning Chip rear dropout system allows for adjustable bike geometry by changing the wheelbase by up to 20mm and the bottom bracket height by up to 4mm. This means you can easily switch between a bike with the responsive, agile handling of a shorter wheelbase and a bike with the confidence and stability of a longer wheelbase just by flipping the Tuning Chip.




Unparalleled ride quality results from the combination of stainless steel and carefully thought out frame geometry. The Warakin Stainless was designed by our engineers in Minnesota and manufactured by top steel frame fabricators in Taiwan.


Warakin’s progressive geometry takes a page from the cross-country MTB playbook. Increased top tube length and a shorter stem maintain stack and reach while providing a lively ‘can-do’ attitude on rougher terrain.


A small port near the bottom of the seat tube allows for the cable routing of a dropper post. If you don't ride with a dropper, you probably won't even notice the port.



Numerous frame braze-ons allow Warakin to accommodate cable routing clamps, three water bottles, fenders, racks, frame bags, and more. Three braze-ons on either side of the fork allow for additional storage.
