DISC BRAKE SUPERBIKE

Looking for every advantage you can get on your way to the podium? The PRsix is wind-tunnel designed plus real-world tested and approved by our team of Quintana Roo triathletes.

The combination of QR's SHIFT+ technology, boat-tail airfoils, and leading-edge absent chainstay gives you superior aero advantages over the competition. PRsix features a wide range of position adjustment to find the perfect balance of aero and comfort with our proprietary integrated stem/fork design and Perfect Position seatpost.

With the precision stopping power of disc brakes you'll stay in aero position longer knowing you have powerful brakes you can trust every time in any condition.

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.

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 atzipp.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.
