The Speedster
Despite its apparent simplicity, the Speedster epitomizes what a Co-Motion tandem is all about; responsive handling, comfort in the saddle, and confidence-inspiring road manners. When you're riding a Co-Motion tandem, you'll feel as though you're still on your single bike. Unlike other brands of tandems, the sense that you're driving a tractor-trailer disappears when you experience the quick and nimble steering of the Speedster. That precision handling summarizes the Co-Motion philosophy as well as the Speedster's character. This tandem is remarkably lightweight and fun to take up long climbs, yet rock solid and stable on winding descents.
Co-Motion's unmatched ride quality is the foundation of our tandem reputation, and we believe in packaging it with beautiful workmanship and finish. No one wants to invest in a machine as well developed as the Speedster without reaping the aesthetic rewards that Co-Motion owners expect. Super precise TIG welded joints, impeccable finish details, and show-quality custom paint are all yours to enjoy even when you don't have the time to take a ride.
This year we have upgraded the Speedster's frame construction with further improvements to our exclusive air-hardening tandem tube package, a cro-moly steel unequalled by any steel alloy used by other tandem manufacturers. As on all Co-Motion models, one-piece top and lateral tubes keep the frame straight and strong with no interruption at the center joints. These double- and triple-butted tubes, made to our stringent specifications, produce a lighter tandem frameset than any prior generation of Cro-Moly tubing. The result is that the Speedster delivers a ride that is crisp and comfortable at the same time.
A roomy stoker compartment, simple three-size system, and numerous stem selections for captain and stoker make a great fitting tandem a reality for just about any team. The Speedster's high level of component specifications will leave you completely satisfied that you own one of the best tandems the world has to offer. And the good news is - you'll be absolutely right.
