Einstein created the theory of relativity while riding a bicycle; had he been aboard Quintana Roo's PRsix Ultegra Di2 Race, he'd have witnessed time slowing as he approached the speed of light. Fully embracing the ultimate in speed, this full-carbon rig blends extensive wind tunnel testing with real-world riding applications to give you a wind-cheating TT machine that's also one of the lightest frames in its class. Boat-tail tube shapes optimize airflow over the entire bike, and QR's Shift+ technology shepherds the wind to the less-turbulent non-drive side to further reduce drag.

One thing E=mc2 tells us is that all matter contains massive amounts of energy. The PRsix proves the equation, as putting even the slightest amount of your weight into the FSA carbon crankset transfers incredible power through Shimano's super-sleek electronic Ultegra Di2 drivetrain, with the energy ultimately manifesting itself in perpetual forward motion toward the finish line. Slick Reynolds Strike carbon wheels effectively operate in a vacuum, as the deep aero carbon rims are nearly impervious to any breeze that hits them.

In addition to poring over every aerodynamic detail and keeping weight as low as possible, Quintana Roo also kept the bike extremely user-friendly. Their proprietary stem delivers a 600mm range of adjustability, and the Profile carbon Aeria bar with carbon T4+ extensions provide even more lightweight position optimization. Plus, traveling is simple: two hex wrenches is all you need to go from bike case to T1-ready. Go ahead, tear a hole in the space-time continuum.
