The Wyvern is our 27.5+ hardtail mountain bike. It’s designed to be ridden hard on any kind of singletrack you can throw at it. It will also fit 29 inch wheels if that’s your cup of tea. It rides well fully loaded with bikepacking gear. It has a tubeset carefully chosen to be as light as possible while still producing a bike you can ride for decades. And like all our bikes, it’s hand built right here in Durango, Colorado.

Thermlx logoPMW logoThe Wyvern is built with Vari-Wall seamless tubing. Vari-Wall has been manufacturing bike frame tubes for more than 20 years out of their Columbiana, Ohio location. Their commitment to American manufacturing and high quality products make them a perfect source for our frame tubes. Most of the frame components, such as dropouts, are sourced from another American manufacturer, Paragon Machine Works in Richmond, CA.
