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 the Belgium Waffle Ride. For others its the ultimate Gran Fondo bike or light tourer that easily transforms to handle the changing terrain.

Drivetrain Options - What Drives You?
You've decided which Co-Motion is right for your kind of riding. Did you know we're also the leader in tandem drivetrain options? These are the available drivetrain options for the Steelhead.

Gear Inches- The descriptions above refer to gear inches for comparison purposes. The term refers to the effective equivalent wheel diameter per pedal stroke. For example, if you're pedaling the Steelhead with SRAM AXS in first gear, each full pedal stroke will produce the equivalent of one wheel revolution of a 23.6" wheel, while the highest gear will produce the equivalent rotation of a 122.6" wheel.
