QR is proud to introduce the QR PR6, 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.
We measure 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.
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:
We have kept the distance and ratios from the front wheel trailing edge to the downtube within a tighter standard deviation than any of our competitors. Most companies are designing the bike around one size and going up and down from there. We've actually calculated this for each size.
Leading Edge Absent:
The PR6 combines QR-innovated SHIFT + with the elimination of a non-drive side chainstay leading edge, while also increasing stiffness.
