The Wyvern is our 27.5+ and 29er hardtail mountain bike. It’s designed to be ridden hard on any kind of singletrack you can throw at it. 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.

Frame Materials

We build our bikes with the finest steel tubing and raw stock in the world. Tubes are selected from several different manufacturers based on exactly what butting profile and alloy we want for that part of the bike.

PMW logoWhat we can’t make ourselves we source from the best machine shop in the industry; Paragon Machine Works. Their commitment to American manufacturing and high quality products make them a perfect source for our critical frame components such as dropouts, headtubes, and bottom bracket shells.
