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.

The Wyvern is made in 4 sizes that should fit the vast majority of mountain bikers. Making them in stock sizes allows us to offer a great price on a handcrafted American made frame. You get all the craftsmanship and attention to detail for half the price and half the lead time.

For the Wyvern, I’ve carefully picked the right blend of pedaling efficiency, responsive handling, stability and playfulness so that it handles very well. It’s a bike that can be ridden aggressively on singletrack or loaded up for a week of bikepacking. If you want to own one hardtail to do it all, this is it.
