Handmade in Eugene, Oregon, Co-Motion's Robusta is one of the lightest and most well-designed tandems out there. Anyone can design a light bike, but constructing a tandem that rides this well and holds as many titles both nationally and internationally is different. Co-Motion's zonally butted aluminum frame is lightweight, ruggedly stiff and rides like a single. Up front, its Alpha Q carbon fork handles brilliantly, steers precisely and cancels out road chatter while the lightweight Rolf Prima Vigor Tandem wheels slice through headwinds and accelerate instantly. And because you and your partner desire the very best, the Robusta sports the world's most sought-after components like a Chris King headset, Alpha Q carbon seatposts, and a Shimano Ultegra/FSA drivetrain.
