Otso Warakin Stainless Frameset

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 bike-packing trip, or afternoon group ride.

STAINLESS STEEL
The supple and smooth ride quality of steel meets the corrosion resistance and lively feel of titanium. Stainless steel is lighter than you think, loads of fun, and ready for your next full day on the saddle. It's a frame material that is as unique and seldom used as it is versatile and excellent for multiple types of riding.

TIRE CLEARANCE
700c? Check! 650b? Double check! 29er? Triple check! Warakin Stainless has massive tire clearance because no two roads are the same. The Warakin Stainless has clearance for 700c x 51mm, 650b x 51mm, or 29" x 2.1" tires. Race gravel with 700c x 38mm semi-slicks, then swaps in 29" x 2.1" for that bike-packing trip with gnarly trails without needing to ride a different bike.

TUNING CHIP™
The Tuning Chip rear dropout system allows for adjustable bike geometry by changing the wheelbase by up to 20mm, bottom bracket height by up to 4mm, and head tube angle by 0.2º. 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. Use the back position for stability and confidence with its longer wheelbase, lower bottom bracket, and slack head tube angle. The front position is ideal for winding singletrack or the CX course with its shorter wheelbase, higher bottom bracket, and steeper head tube angle. The center position is the best of both worlds.

TOP PERFORMER
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.

PROGRESSIVE GEOMETRY
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.

DROPPER FRIENDLY
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.

FOR THE LONG HAUL
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.
