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 professional team, which is known to choose its equipment exclusively from a performance perspective and has now achieved numerous World Tour victories on Princeton Carbon Wheels.

The Peak 4550 Evolution is the perfect aero wheelset for climbers and riders looking for agile, easy-to-accelerate wheels. The rim shape is based on the findings of the latest Wake 6560 Aero wheels. This ensures outstanding crosswind stability and maximum aerodynamic efficiency for a wheelset with a profile height of up to 50 millimetres. Compared to the last generation, the inner rim width has been increased to 21 millimetres with an outer width of 28.2 millimetres. This means that the Peak 4550 wheels integrate 25-28 millimetres in a particularly aerodynamic way. Despite the reduced rim weight of 420 grams, the rigidity of the wheels has been increased. Thanks to the tubeless rim bed without holes, tubeless tires or folding tires with tubes can be used without rim tape. The absence of holes has also made it possible to make the rim well thinner and lighter, while still giving the rim greater stiffness compared to a classic rim well.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.
