PRINCETON CARBONWORKS wheelset 28" Road Dual 5550 Evolution | Tactic Racing TR01 hubs | Matte / Black
Behind Princeton Carbon Works are the founder Marty Crotty and the three co-founders Brad Werntz, Harrison Macris and Paul Daniels. Marty, a former college rower and Ironman triathlete, had the idea of designing his own original high-end aero carbon wheels. Together with his then acquaintance Brad Werntz, at the time a rower and student majoring in mechanical and aerospace engineering, they developed the first ideas for a revolutionary high-profile wheel in 2012. Also from rowing circles, they brought Harrison Macris, a mechanical engineering student from Boston, and marketing expert Paul Daniels on board. Since the market launch of the Wake 6560 wheelset in 2017, Princeton wheels have been causing a stir with their design and excellent test results. Another milestone in the company's history is the partnership with the Ineos-Grenadiers pro team, which is known to choose its equipment exclusively from a performance perspective and has since achieved numerous World Tour victories on Princeton Carbon Wheels.
With the Dual 5550, Princeton left familiar territory. Aerodynamically optimized for 30 to 32 millimetre wide tires, it is aimed at cyclists looking for maximum performance on and off paved roads. Its robust rims also allow it to be used on gravel bikes with tires up to 50 millimetres wide. The legendary and dreaded Paris-Roubaix spring classic provided the impetus for the development of the Dual 5550, for which the Ineos Grenadiers were looking for the optimum wheelset. Thanks to the tubeless rim bed without holes, tubeless tires or folding tires with tubes can be ridden without rim tape. For the greatest possible safety in all conditions, Princeton continues to rely on rims with hooks, which means that the rims can be used without tire pressure restrictions and the maximum permitted values of the tire manufacturers can be used. The wheels are spoked with Sapim CX-Ray bladed spokes and ultra-light Tactic Racing TR01 hubs with ABEC 7 ceramic bearings.
