Steelhead

The Steelhead is a unique tandem species, just like the native fish here in the Pacific Northwest. It’s born near cold water tributaries with gravel under its belly and ready for adventure.​ This is one versatile road bike, whether the road is paved, double track or covered with gravel. For some this tandem will be the ultimate gravel bike for weekend explorations or racing the Land Run 100 and Dirty Kanza. For others its the ultimate Gran Fondo bike or light tourer that easily transforms to handle the changing terrain. Utilizing our exclusive Reynolds 631 tandem steel tubing and a brand new Co-Motion designed thru-axle carbon fork, rack and fender mounts, this is the perfect all roads and any weather tandem.
