After releasing their impressive PRsix, Quintana Roo decided to follow it up with the PRfive, a lower-priced model that, in many respects, improves on the original. The frame design is largely identical, with the big departure being a traditional fork. This allows for greater flexibility in choosing your position, as any 1 1/8” stem will work. And it makes travel easier as well.

The frame comes out of the same molds, which means the aerodynamic performance is almost identical. The fork itself gives you the option of just about any aero brake on the market, with threading for direct-mount brakes as well as a center hole mount for more traditional brakes. And this flexibility also extends to the under-the-bottom bracket rear brake, which can take Magura, Shimano, Tri-Rig, TRP, and others. The frame comes with Shimano Ultegra direct mounts.

The downtube is where the PR series bikes have major innovations. The fork crown notch is a great touch, but it is only the obvious. Not all downtubes, not all aero downtubes, are created equal. The PR bikes have two technologies going for them. The first is their Shift+ design, which shifts the air flowing around your downtube to the left, the cleaner side of the bike. This minimizes the air getting batted around by the drivetrain. The second is a static downtube orientation. The downtube is quietly one of the big variables in aerodynamics, because the distance from the front wheel to the tube typically changes over a size run, with the smaller sizes being more aero in zero-yaw conditions, and the bigger sizes having more of a sail effect in crosswinds. By keeping the distance between the trailing edge of the front wheel a consistent distance from the downtube, the bikes are more consistently aero across the size run. On the backside of the downtube, the boat tail shaping works as a better shroud for water bottles, costing only 3.9 watts vs. up to 6.3w for the competition.
