Princeton CarbonWorks Grit 4540 Wheelset


The newest member of the family, the GRIT 4540 was designed to recalibrate a rider's expectations of a carbon wheelset. Lightweight, stiff, versatile, snappy, fast, stable. The GRIT 4540 is ideal for climbing and all-purpose road or gravel/CX.

Taking experience from the 6560, Princeton CarbonWorks launched the GRIT with its variable depth sinusoidal cross-section, for unrivaled cross-wind stability. The GRIT also features a slightly varying width to the profile, and optimized 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. 21mm hook to hook and 29.9mm at the widest point. Like the 6560, the 4540 takes advantage a uniform, hole-less tire bed. By removing holes from the tire bed, the wheel becomes incredibly stiff while allowing for a thinner tire bed making the wheel lighter, and stronger.
