Quintana Roo PRsix Ultegra Di2 Triathlon / Time Trial Bike - Aero 72
QR is proud to introduce the QR PRsix, a bicycle alone in approach and backed by a trusted heritage of innovation in triathlon. Light, agile, and responsive in a way largely considered impossible for the superbike category, the PR reinvents the expectation of overall ride handling and power-to-pedal efficiency for a bike in the elite tier of aero/drag ratio.
Quintana Roo measures variables that are critical to bike development in the SuperBike category. It's more than just a wind-tunnel test. It's comprehending the data and utilizing our knowledge to create a bike that pushes the boundaries of what is possible.
Boat Tail: The PR6's Boat Tail tube shape further closes off Kamm Tail edges. That means less vacuum and more efficient airflow on all relevant tubes.
Fixed Aero Downtube: The PR6 combines QR-innovated SHIFT + with the elimination of a non-drive side chainstay leading edge, while also increasing stiffness.
Leading Edge Absent: The new, improved braking system has more powerful returns, is easier to adjust and accommodates a wide range of aero wheels.
Easy Assembly: 2 hex wrench sizes get the bike up and running while some competitors use more than 10 different
True Flexibility: 2 dropout choices - vertical or horizontal AND unlimited cockpit compatibility - the 31.8 clamp size gives you the option of using ANY base bar/clip-on bar combination or ANY integrated cockpit by any manufacturer. Additionally, the PR6 gives you the option of using any brake from Shimano, TRP, Magura, and TriRig.
Cockpit Adjustability: X/Y adjustable QR proprietary stem with precise, easy-to-use positions (as shown below) to quickly and easily make any range of adjustments without having to buy new components, stems, or bars to achieve a different front-end position. Add an additional 7.5 cm with the Profi le Aria bar.
