QR-549 | PRfive2 105 Di2 12 spd with Ultegra Crank and Shimano RS-171 Wheels. Aeria Hydration, Cool Mint paint with Black graphics, Size 52
One of our most popular elite tri bike platform gets a refresh. Big-time.
The PRfive was designed for practical use by real world triathletes, while also standing at the forefront as a top-end machine of multisport speed. Engineered for aero advantage, made light weight for the hilliest courses and easy to fit, it has been a favorite in the QR stable. With the new PRfive2 Disc, you get that—and more.
The revamped PRfive2 Disc takes every bit of advantage from its predecessor—then it gets lighter, adds the security of a T47 BB system, includes the clean integration of a Di2 frame port and provides option for integrated hydration. And we can all drink to that!
In this new iteration of the PRfive2, we’ve added the security of a threaded T47 bottom bracket, and the clean convenience of frame-integrated Shimano Di2 charging port. We’ve dropped 120 grams from our previous frame—a seven percent weight savings. And with the addition of the sturdy T47 bottom bracket, we’ve increased frame stiffness by 12 percent, making for a higher-performing platform than its predecessor when climbing and accelerating.
And of course, the PRfive2 Disc is designed to travel with ease. Retaining a traditional aero fork, stem and basebar interface, the PRfive2 Disc assembles and disassembles with ease. All you need are standard tools and minimal mechanical acumen to adjust your cockpit or pack your bike for the races.
Get all the practical function like frame-integrated nutrition and hydration storage. Get disc brake stopping power. Get aero-engineered, wind tunnel-proven speed that rivals that of our competitors. Get it all with the convenience that a standard cockpit interface brings. Get an extensive range of frame size options to accommodate nearly every triathlete. Get a massive range of frame and graphic color options, at no extra charge. And get it delivered right to your door, for less dough than the other guys. The PRfive2 Disc delivers features (and unrelenting speed) at a price our competitors simply can’t match.
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.
