PRfive Disc

Size Guide

€4.200,00

ELITE DISC-BRAKE TRIATHLON BIKE

We designed a disc bike for real triathletes—it's aero, stable, lightweight and adjustable with only two wrenches. Starting at €4.200, 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.

SHIMANO ULTEGRA Di2 ELECTRONIC
Market-leading electronic gear shifting thanks to the Di2 system and trickle-down technology from professional-level Dura-Ace groupsets. This system ensures shifting accuracy, which provides crisp and precise shifts with every push of a button. No adjustment is required once setup. Instead of mechanical cables, high-end Di2 electronic wires relay your gear selection instantly with a push of a button. Upgrading to Di2 based system places gear shift buttons on both your aero bar extensions and base bars.

SHIMANO ULTEGRA MECHANICAL
New ULTEGRA R8000 series is "pro-proven" as it is a direct trickle down from DURA-ACE mechanical groupset. As a triathlon bike component, the stress-free operation is one of the most important feature to lead all day riding comfort with braking and shifting. Mechanical groupsets do not feature gear selection changes to be made from the bars as the shifters are placed on the ends of the aero bar extensions. Upgrading to Di2 groupsets allows for electronic shifting buttons to be placed on base bars and aero extensions.
ZIPP 404 NSW DISC
The NSW Tubeless Disc-brake wheels are aerodynamically optimized for wide tires to meet the performance needs of modern riders in search of low rolling resistance and high comfort. Throughout the development process our engineers carefully considered the rim-to-tire interface and how specific tire and rim widths affect aerodynamic performance. NSW technology adds to this legacy enhanced aero performance and tubeless compatibility, all with the benefits of disc brakes. Learn more at zipp.com.

ENVE SES 7.8 DISC
Disc brakes are beginning to appear on the most aerodynamic bikes in the world and the SES 7.8 is ready. While most wheel manufacturers simply repurpose their rim brake optimized wheel models into disc brake wheels by covering brake tracks with decals and adding disc hubs and more spokes, this leaves substantial amounts of performance on the table. A revolutionary new disc brake specific, aerodynamic, carbon fiber triathlon and time trial wheelset. The SES 7.8 Disc is both aerodynamically and structurally optimized for use with disc brakes. Visitenve.com/products/ses-7-8/discfor more information.

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 AR58/62 DISC
The Reynolds AR58/62 disc brake carbon road bike wheelset provides the ultimate aerodynamic advantage for time trials and triathlons. The 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.

SHIMANO RS170 DISC
The Shimano RS170 Road/Cyclocross wheelset for tubeless with disc Center-Lock and 12mm E-thru version - Offering all the technology of Shimano wheels at an economical price.
