We designed a disc bike for real triathletes—it's aero, stable, lightweight and adjustable with only two wrenches. Starting at $4,599, the new PRfive Disc competes at the highest level, with elevated safety and braking capabilities in any condition. With increased lateral stiffness and a more aerodynamic design, you'll be able to output more power while conserving energy for the run. The PRfive Disc gives athletes the confidence they need to perform their best.
Previous winner of an Interbike Award for Triathlon Innovations of the Year, the PRfive represents all the best aero benefits of our PRsix superbike - with its design moved to a standard front end - making it not only easier for the average triathlete to mechanically work on and travel with, but also making it more affordable
For use in a stationary trainer, a specific thru-axle will need to be ordered. The rear thru-axle is an E-thru standard M12x1.5.

SHIFT+ Aerodynamics: 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.
Thru-Axle Disc Brakes: Stopping power and braking modulation that increases safety and rider confidence. Slight changes in frame design to allow for thru-axle disc brake systems, increases the stiffness of the bike allowing for greater power transfer and acceleration.
Perfect Position Seatpost: The Perfect Position seat post allows you and your fitter to dial in the perfect position. Our seat post gives you the freedom to make precise adjustments easily without having to buy new components to achieve a comfortable fit. All QR bikes are completely customizable, and can be fit to get you in the perfect comfortable aero position so you can fly.
30T Carbon Fiber Layup: PRfive features a 30T modulus carbon fiber that's a perfect combination of lightweight, stiff, and durable.
Top Tube Storage Box: 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.
QBox Rear Storage: 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.
Disc Brake Technology: Stopping power and braking modulation that increases safety and rider confidence. Slight changes in frame design to allow for thru-axle disc brake systems, increases the stiffness of the bike allowing for greater power transfer and acceleration.
