In the context of time trial and triathlon bicycle design, we have reached a point of maturity in which the majority of the recent decade’s aerodynamic innovations have been incorporated into the offerings of most major manufacturers.  The goal of good aerodynamic design is to manage airflow as efficiently as possible; normally, this is done through careful attention to narrow frontal profiles and clean trailing edges.  Quintana Roo, however, has added an exciting component to this calculus.  Correctly reasoning that the drive side of a bicycle, with its rotating chainrings and hanging front derailleur, is less aerodynamic than the opposite side of the frame, Quintana Roo designed its CD 0.1 frame with “shift technology,” which directs airflow away from the right side of the crankset by carefully curving the downtube.

The result is an elegantly designed—and extremely fast!—frameset that offers advantages not seen in any other brand.  For more information, visit:
