Co-Motion Java


Find out what your missing when you leave the pavement behind, and return to the dirt roads and trails.  The Java is a great dual purpose  tandem.  You can cruise the trails with the 29×1.9 tires.  But switch the tires and tubes to a more civil 700×35 and you can ride the roads all day long in comfort.

Da Vinci Symbiosis XC




This bike is a BEAST whether you are blasting down a fire road or pushing hard in your favorite race. The Symbiosis has become the benchmark for off road/cross country tandems. With race wins in the 24 Hour of Moab, Leadville 100, and Vail Ultra 100 you can see that the suspension does its job, and delivers a great ride in the roughest trail. With the drop top tube you get a much better standover and suspension adjustment. It is now available in both 27.5 or 29 wheels. My wife and I had a 27.5 plus size and enjoy riding the fire roads trails of northern Michigan

Santana Team Scandium


Our custom tubeset starts with the strongest grade of aluminum, 7000 series, then adds scandium for increased strength and stiffness. This allows us to use very thin butted tubes for light weight and superior ride quality. The Bi-Laminate feature of the Team Scandium adds carbon seatstays and co-molded carbon/scandium down and bottom tubes for the vibration damping effects of dissimilar materials and a beautiful, unique look. Also available with our Z-Couplers for easy travel with the Safecase system. Starting at $7,595 with the Standard build kit upgraded with carbon cranks and Ultegra 2×11 drivetrain in your choice of gearing from a hill leveling 34/50 11-42 to a racy 39/53 11-28.

Santana Spirit Tandem


The Spirit is our steel frame built from Columbus’ most advanced alloy drawn into custom sized and butted tubes engineered to provide the legendary ride of steel with the lateral stiffness, confident handling, and power transmition Santana tandems are renowned for. This incredibly strong alloy allows us to use tubes as thin as 6/3/6 gauge creating the lightest possible steel tandem. Also available with our Z-Couplers for easy travel with the Safecase system.
