Warakin Stainless
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.
