The next generation of the award-winning PRsix Disc has arrived – introducing the PRsix2. The PRsix2 takes all of the innovative technologies and aerodynamic qualities of the PRsix and maximizes them with additional features, integrated hydration system, and a lighter and stiffer frame. With each feature fully utilized, you are reaping the benefits of and improving the performance of the bike as designed by the exclusively triathlon engineers at QR.

We pride ourselves on listening and reacting to our athletes’ needs, thus the creation of the PRsix2. With an 11% increase in stiffness and 10% lighter frame from the current PRsix Disc, T47 bottom bracket and integrated enhancements, this bike takes performance and simplicity to the next level. The PRsix2 was designed to incorporate more aero-enhancing benefits with an integrated hydration system, invisible cable routing with integrated Di2 port and more.

The PRsix2, the fully loaded aero machine, will help you break new boundaries and set even more new PRs.

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.

*QR’s Aeria Hydration system has been designed specifically for the PRsix2 and is not compatible with other QR models or size 48 bikes.
