Princeton CarbonWorks Wheels

Princeton CarbonWorks was built by competitive rowers who became world-class triathletes — engineers who understood carbon fiber from boats before they applied that knowledge to bicycle wheels. Founded in 2012 in Massachusetts by Marty Crotty, Harrison Macris, and Brad Werntz, and manufactured in Mystic, Connecticut, Princeton has earned Team INEOS sponsorship, featured on Filippo Ganna’s world championship pursuit bikes, and put wheels on the start line at the Paris Olympics.

The RA Cycles lineup spans the full Princeton range: the aero Wake 6560 EVO designed around 28mm tires, the lightweight Peak 4550 EVO for climbing and versatile road use, the Grit 4540 EVO optimized for gravel and wider tires, the deep-section Mach 7580 for triathlon and time trials, and the all-road Dual 5550. Most builds are available with Princeton’s own Tactic TR01 hubs or White Industries hubs.

About Princeton CarbonWorks

Princeton CarbonWorks traces its roots to competitive rowing — the founding team brought carbon fiber engineering insight from racing shells to bicycle wheels. Founded in 2012 in Massachusetts by Marty Crotty, Harrison Macris, and Brad Werntz, and manufactured in Mystic, Connecticut, the brand has earned partnerships with Team INEOS and featured on Filippo Ganna’s pursuit world championship bikes. The Wake 6560’s name is a direct nod to the founders’ rowing background. Visit Princeton CarbonWorks’ official website for the full technology breakdown.

The RA Cycles Princeton CarbonWorks selection covers four distinct wheel platforms. The Wake 6560 EVO is the flagship aero road wheelset — designed around 28mm tires and tuned for UCI mass-start racing. The Peak 4550 EVO is the lightweight climber, with a 420g rim and 21mm internal width. The Grit 4540 EVO targets gravel and wide-tire road use, with a 385g rim and a hooked, hole-less tire bed built for tubeless. The Mach 7580 goes deepest for triathlon and time trial riding. Hub options across the lineup include Princeton’s in-house Tactic TR01 or White Industries hubs.
