Princeton Carbonworks Grit 4540

"I recently upgraded my Trek Domane SL-8 stock Bontrager Aeolus Pro 3 wheels to a set of GRIT 4540 wheels with White Industries hubs and I’ve been thrilled with the results – gaining both speed and confidence. The bike rolls much more smoothly, absorbs bumps even better than before, and handles the gusty cross winds by the shore much better than my shallower Aeolus Pro wheels." - Matt (verified customer)

Princeton Carbonworks Grit 4540

The newest member of the family, the GRIT 4540 was designed from the ground up to recalibrate your 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). How do we do it? Taking experience from the 6560, we launched the GRIT with our variable depth sinusoidal cross section, for unrivaled cross wind stability. We 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. Next level stuff? Try 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 us to make the tire bed thinner (lighter) while providing greater hoop stiffness (stronger). Oh yeah, no more tubeless tape either (YOU’RE WELCOME).
