Conquer Every Terrain with Unyielding Strength

Elevate your off-road adventures with the remarkable Princeton Carbonworks Grit 4540 wheels. Engineered to excel in rugged environments, these wheels are a harmonious blend of cutting-edge technology, robust construction, and dynamic performance, making them the ultimate choice for trailblazers and adventurers. Designed from the ground up to recalibrate your expectations from an all-road carbon wheelset.

Lightweight? Got it. Amazing stiffness? Check. Versatile, snappy, fast, stable? Always.

How do we do it?

Taking experience from the 6560, we launched the Grit with our variable depth cross section for unrivaled cross wind stability. We also introduced a slightly varying width to the profile, and optimised our carbon layup, focusing around high stress areas.

The nipple bed has been completely re-engineered to provide greater carbon thickness in that area while removing material where not needed: 21 mm hook to hook and 29.9 mm at the widest point.

The wheelset is built with a uniform, holeless tyre bed. By removing holes from the tyre bed, the wheel becomes incredibly stiff (holes and carbon aren’t best friends). That allowed us to make the tyre bed thinner (lighter) while providing greater hoop stiffness (stronger). Oh yeah, no more tubeless tape either.
