Princeton Grit 4540 EVO Disc Brake Wheelset w/White Industries Hubs

The Princeton Grit 4540 EVO Disc Brake Wheelset w/White Industries Hubs was built for riders who refuse to simplify their routes. Not strictly a road wheel, not strictly a gravel wheel — something more useful than either label suggests. Princeton CarbonWorks designed the Grit 4540 EVO around a straightforward conviction: aerodynamic performance and real-world durability belong on the same wheelset, and the rider shouldn't have to choose between them.

The rim profile is where that philosophy becomes engineering. At 45mm deep at the front transition and 40mm at the brake track, the variable-depth construction isn't a styling decision — it's a calculated trade-off between aerodynamic efficiency and crosswind stability. Deep-section wheels earn their reputation for speed, but they also earn their reputation for nervous handling when the wind picks up or the road tilts sideways. Princeton's variable-depth approach is designed to recover some of that lost composure without surrendering meaningful aerodynamic gains. The tubeless-ready carbon construction extends that logic further — run lower tire pressures, and the wheel works with the terrain rather than against it, absorbing road buzz and improving grip on surfaces that punish a rigid, over-inflated setup.

Then there are the hubs. White Industries builds out of Petaluma, California, and they have spent decades earning a reputation that doesn't depend on marketing. Precision machining, quality bearings, and a build standard that serious riders trust for the long haul. Pairing White Industries hubs with Princeton's carbon rims produces a wheelset where both the aerodynamic performance you can feel at speed and the mechanical integrity you rely on after thousands of kilometers have been taken seriously. This is a wheel that rewards consistent, demanding use.

Design Benefits

1. Variable-Depth Rim Profile: The asymmetric rim — deeper at the front transition, shallower at the brake track — is designed to balance aerodynamic efficiency with real-world handling. Where a uniform deep-section rim can feel unpredictable in crosswinds, Princeton's variable geometry is intended to keep the front end composed when conditions shift, making the speed you gain aerodynamically more usable across a wider range of riding situations.
2. Tubeless-Ready Carbon Construction: Running tubeless on these rims opens the door to lower tire pressures without the flat-risk penalty that comes with traditional tubes. Lower pressure means more tire contact with the road surface, better vibration damping, and improved grip — tangible advantages on rough pavement, loose gravel transitions, or any surface where tire compliance matters as much as rolling resistance.
3. White Industries Hub Quality: White Industries has built a following among riders who measure hub quality in decades, not seasons. Their machining tolerances and bearing quality translate to smooth engagement, predictable power transfer, and the kind of longevity that makes a premium wheelset a long-term investment rather than a consumable. These hubs are serviced and rebuilt rather than replaced — an important distinction for riders who log serious miles.
4. Broad Drivetrain Compatibility: Available with Campagnolo, HG11 (Shimano/SRAM 11-speed), and XDR driver options, the Grit 4540 EVO fits cleanly into most modern road and gravel drivetrains. Whether you're running a Campagnolo groupset or switching between SRAM's newer 12-speed ecosystem, there's a hub configuration that slots in without compromise.
5. Versatile Riding Range: The 4540 EVO's depth and tubeless construction place it squarely at the intersection of road speed and mixed-surface capability — usable for fast group rides and gran fondos where aerodynamics matter, and composed enough for routes that wander onto chip-seal or packed gravel. It's a wheelset that covers real riding territory rather than a narrow performance window.

Final Take

The Princeton Grit 4540 EVO is built for the rider whose routes don't fit a single category — someone who wants meaningful aerodynamic performance on the fast sections without sacrificing stability or durability when the road gets complicated. Paired with White Industries hubs and available in a range of finishes and drivetrain configurations, this is a carbon disc wheelset designed to be ridden hard and kept for a long time.
