When only seconds can separate you from setting a new PR, breaking a World Record, or hitting the top step of the podium - every watt counts. The PRsix Disc Superbike is wind-tunnel tested and real-world approved. It features "no-gimmicks" aerodynamic shaping developed by engineers who utilized their experience in the triathlon, cycling, and aerospace industries.
The ‘motor’ of the bike—the drivetrain—is the very thing that can slow it down, by catching wind. With SHIFT+, we’re able to offset our Static Aero Downtube in a way that moves airflow away from the ‘dirty’ (drivetrain side) to the ‘clean’ side (non-drive side). Not only does this give you a major aero advantage, but it also lends stability mile after mile. It’s a win-win in the wind.
Integrated stem and fork design creates a clean look and provides for maximum aerodynamics. The 2.0 stem, developed by Quintana Roo, allows for base bar height adjustments with no additional components needed.
Dial in your cockpit with our adjustable QR proprietary stem or adjust our Perfect Position seat post to get as steep as you'd like. It gives you the freedom to make precise adjustments on the fly without having to buy new components, stems, or bars to achieve a different front-end position.
With 40T high-modulus carbon fiber we've maximized stiffness and power transfer on the PRsix and PRsix Disc models while maintaining a lightweight, durable frameset.
Two sizes of QR Top Tube Storage Boxes are available, a 70.3 version and 140.6 version. Room for all your training and race day nutrition needs; like gels, Base Salt tubes, and electrolyte tabs. The QR Top Tube box is standard on all PRseries bikes and integrates with the QR 2.0 stem system for maximum aerodynamics.
Rear storage box developed by QR that actually improves the overall aerodynamics of the frame and makes the bike faster. The QBOX allows for storage of your spare tube, CO2, tire levers, and an extra gel or two. It also features a rear taillight with blink and constant-on modes. QBOX attachment brackets utilize an industrial grade adhesive developed by 3M, so your QBOX will be safely and securely attached to the frame.
"The most incredible characteristic of this bike is that the more you speed up, the more the PRsix is stable and comfortable. The feeling is really unbelievable..."
