Otso Arctodus SLX
Product Details
The Otso Arctodus, named after the ferocious short-faced bear of ancient North America, is tough and adaptable. The frame is constructed from Chromoly steel and the fat fork is lithic carbon which provides clearance for 26x5in tires. This build features the same tuning chip found on the Otso Voytek allowing the rider to dial in their wheelbase or swap the wheelset for 29 or 27.5 plus.
Our Arctodus build includes Shimano SLX M6100 brakes for increased performance, reliability, and easy maintenance.
Designed as a destination fat bike, the frame and carbon fork are covered with braze-ons to allow virtually endless cargo configurations. Utilize this bike to traverse snow-covered trails or for added comfort and stability on rough terrain.
