#46 | PRfive Disc Ultegra Di2 with Ultegra Crank Upgrade, Size 52
We designed a disc bike for real triathletes—it's aero, stable, lightweight and adjustable with only two wrenches. Starting at $4,499, 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, 163mm long.
