Princeton CarbonWorks Grit 4540 Evolution represents the brand’s continued push into high-performance gravel and all-road wheel design. Engineered for riders who demand speed, control, and durability across mixed terrain, the Grit 4540 Evolution delivers a refined balance of aerodynamics, strength, and ride compliance.
Developed as part of Princeton CarbonWorks’ commitment to aerodynamic innovation beyond traditional road cycling, the Princeton CarbonWorks Grit 4540 Evolution platform adapts the brand’s advanced design philosophy to gravel riding. With the Evolution update, the wheelset benefits from improved structural efficiency, reduced weight, and enhanced stability making it ideal for modern gravel racing and endurance adventures.
The Grit 4540 Evolution features a progressive dual-depth rim profile, with a shallower front rim (~40 mm) and a deeper rear rim (~45 mm). This configuration enhances handling and confidence on unpredictable terrain. The shallower front wheel improves steering precision and control, while the deeper rear wheel maximizes power transfer and maintains speed on fast gravel sections.
Aerodynamically, the Princeton CarbonWorks Grit 4540 Evolution is optimized to perform efficiently even at lower speeds and variable yaw angles commonly experienced in off-road conditions. The refined rim shaping reduces drag while maintaining predictable handling in crosswinds, giving riders confidence across open gravel roads and technical sections.
The rim dimensions are purpose-built for wider gravel tires. With a 21 mm internal width and a broad external profile, the wheelset pairs seamlessly with 30–50 mm tires, improving traction, comfort, and rolling efficiency over rough surfaces. The updated carbon construction enhances impact resistance while maintaining a responsive ride feel.
Versatility remains a core strength of the Princeton CarbonWorks Grit 4540 Evolution. The wheel features a hooked, hole-less tubeless-ready rim bed, allowing riders to run both tubeless and clincher setups without rim tape. This enables lower tire pressures for improved grip and comfort while maintaining reliability in demanding conditions.
Premium components complete the build, including Sapim CX-Ray spokes and Sapim Secure Lock nipples, ensuring durability and consistent performance even under harsh riding environments. The result is a wheelset that is fast, stable, and capable perfect for riders pushing the limits on gravel, all-road, and endurance terrain.
