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. Many of our frame components such as head tubes and bottom bracket shells are machined in house.

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.

For 2020, we’ve updated the Wyvern’s geometry. Years of riding and client feedback have led us to subtle tweaks in the geo that we believe make it just right. We’ve also added a size M/L to the lineup, for all those folks who are always between medium and large.

For the Wyvern, we’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.
