CONSIDERING DISC BRAKES?

PRFOUR DISC

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 $3,149 — 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 adapter will need to be ordered. The rear thru-axle is an E-thru standard M12x1.5, 142mm long. The adapter will be specific to the trainer you own, so please check with the trainer manufacturer if you have any questions.

HED VANQUISH 6GP
The co-developed Vanquish 6 GP wheelset takes QR’s disc-brake triathlon bikes to the next level of performance. Made in HED’s Minnesota factory, the Vanquish 6 GP undergoes an in-depth quality control process. The proprietary wheels use the same patented rim shape that HED uses for all of its disc-specific wheelsets. The 6 GP shape is all-new, with a 30mm external width (21mm internal width). This results in a superior aerodynamic performance with 23-28mm tires.

REYNOLDS AR 58/62 DISC
The Reynolds AR58/62 disc brake carbon road bike wheelset provides the ultimate aerodynamic advantage for time trials and triathlons. The tubeless-ready rims are individually optimized for front and rear. The front is narrower to reduce frontal area and shaped to deliver stable crosswind handling. The rear is built with a 21mm rim channel to fit wider tires for reduced rolling resistance and the 61mm heights provides maximum lift to sail through the wind. The Reynolds AR58/62 Disc come with Reynold's lifetime warranty.

SHIMANO RS170 DISC
The Shimano RS170 offers excellent rolling performance and is designed to provide the highest levels of braking performance thanks to the disc brake system. Equipped with the Shimano Centre Lock disc brake technology, this wheel will supply the rider with fast acceleration, stability and stiffness, combined with exceptional braking control.

Can I make changes to the build kit?
Absolutely. Our bikes are built to order so you can customize however you'd like. If there are components you'd really like on your bike but don't see them offered live-chat or contact us for availability and a custom quote!

Can I have a different length stem, crankarms, or different gearing?
We spec different length components on our bikes based on common lengths per each size of bike. If you are looking to specify what length components or the gearing you'd like on your new Quintana Roo just live-chat or contact us and we'll get you started on a custom order.

I received my Di2 bike, but the system isn't charging?
Triple check the seatpost battery/Di2 wire connection. Many times even though you think you have the wire firmly connected, give it another push and 9 times out of 10 the system comes to life.

What kind of thru-axle do I need for my stationary trainer?
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.

How much does shipping cost?

"I feel that the number of relevant bike brands in no-draft triathlon have whittled down to 8. Quintana Roo is one of those relevant brands. In fact, if you narrowed the brand list to 4, it’d make the cut. This new bike, the PRfour Disc, is an advertisement for why that is. This is a disc brake triathlon bike complete for under $3,000."
