PRsix USA Limited Edition Bike

The PR Six Series

2016
Limited Edition USA Bike

Limited Edition USA Bike also includes the matching Qbox. Qbox included with PRsix i2 bikes The Qbox actually makes your bike more aerodynamic (rather than the drag laden myriad of options that have existed to this point). A bike size specific, storage system that doubles as a safety beacon and can be turned on or off without leaving the saddle. Qbox included with PRsix i2 bikes and is compatible with all PRsix builds.

Overview


BOOK SMART

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.

Boat Tail: The PRsix's Boat Tail tube shape further closes off Kamm Tail edges. That means less vacuum and more efficient airflow on all relevant tubes.

Static Downtube Orientation: 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 PRsix combines QR-innovated SHIFT + with the elimination of a non-drive side chainstay leading edge, while also increasing stiffness.

STREET SMART

We know race day is more than just the day you swim, bike, and run. It's time spent breaking down, packing, and being able to make quick adjustments without the need for an engineering degree.

Easy Assembly: 2 hex wrench sizes get the bike up and running while some competitors use more than 10 different sizes.

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 PRSix 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 Profile Aeria bar.
