The best triathlon bike lineup just got better. Quintana Roo has been at the forefront of incorporating disc brakes into its high-performance PRseries triathlon bikes with the PRsix and PRfive models. We’re now excited to introduce a third disc brake triathlon bike model, the all-new PRfour Disc.

Featuring the same aerodynamic frame shape as our pro level PRsix Disc superbike, the stopping power and control of disc brakes, and a starting price of €3.050 — the PRfour Disc is the most affordable and technologically advanced disc brake triathlon bike available to triathletes.

We developed the PRfour Disc featuring a mix of Shimano 105 11-speed components with TRP Spyre mechanical disc brakes for real triathletes looking for disc brake advantages at a price they can afford, without sacrificing performance or reliability.

Not only do disc brakes add to the stopping power and consistency of braking in any condition, they also increase the lateral stiffness and stability of the bike with the addition of oversized thru-axles. With the combination of QR's wind-tunnel developed SHIFT+ technology, boat-tail airfoils and leading edge absent chainstay, the PRfour Disc gives you the ability to bike faster, efficiently output more power, and conserve energy for the run. It's designed with a standard front end, no crazy integrations, making the PRfour Disc easier to mechanically work on and travel with. Plus, stand out and choose between four ultra-bright graphic colors on a stealthy matte black frame!

An all-out race bike at an affordable price—the PRfour Disc gives athletes the confidence they need to perform their best and set new PR's.

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, 142mm long.
