Description

Advanced aerospace engineering facilitates better speed through the breakthrough of dynamic cross-section variability – Princeton Carbonworks wheels yield lower drag and reduced effects of vortex shedding. Optimized mechanical design paired with advanced manufacturing increases stress distribution and enables weight reduced layup schedule.

When Princeton CarbonWorks launched the  WAKE 6560, it broke industry benchmarks and forced discerning riders, like World Time Trial Champion Filippo Ganna to recalibrate aerodynamic, strength, stability and weight expectations. In 4 years of research and development Princeton Carbonworks wheels were wind tunnel confirmed, road tested, gravel verified and race proven.

The GRIT 4540, was designed from the ground up to recalibrate your all-road wheel expectations from a carbon wheelset. Lightweight? Got it. Amazing stiffness? Check. Versatile, snappy, fast, stable? Always. Ideal for climbing and all purpose road OR gravel/CX (mixed terrain, gravel, cyclocross).

Princeton Carbonworks designed the GRIT with variable depth sinusoidal cross section, for unrivaled cross wind stability.   They also introduced a slightly varying width to the profile, and optimized 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. 21mm hook to hook and 29.9mm at the widest point. They also have a uniform, hole-less tire bed. By removing holes from the tire bed, the wheel becomes incredibly stiff (holes+carbon aren’t best friends). That allowed them to make the tire bed thinner (lighter) while providing greater hoop stiffness (stronger). Oh yeah, no more tubeless tape either. The GRIT 4540 is laced to White Industries, Tune or DT Swiss 180EXP hubs Tubeless and podium ready.  Current lead times or orders is approximately 2 weeks.
