An Interbike nominee for Triathlon Innovation of the Year, this Quintana Roo uses Shift + technology on the downtube to divert airflow away from the drivetrain to the non-drive side, where there's more clean air for improved aerodynamics. You'll also notice a big difference in the chainstays, with the non-drive side being much wider.
The frameset retails for about $3,200, and an Ultegra race build starts at $4,800, which should also rank it among the fastest bikes dollar-for-dollar that you'll find.
