Ivy League, All-Road, Rim-Brake Wheel Design

The newest member of the Princeton CarbonWorks 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 they do it? Taking experience from the 6560 model, Princeton CarbonWorks launched the GRIT with their variable depth sinusoidal cross-section, for unrivaled crosswind stability. They also introduced a slightly varying width to the profile, and optimized their 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 that was not needed. 21mm hook to hook and 29.9mm at the widest point.

Next-level stuff right? 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 CarbonWorks to make the tire bed thinner (lighter) while providing greater hoop stiffness (stronger).

Oh yeah, no more tubeless tape either (YOU'RE WELCOME). The GRIT 4540. Tubeless and podium ready. Reserved for those with GRIT

Note: These wheels are also offered with TUNE, Chris King R45 Standard, Chris King R45 Ceramic, DT Swiss 180EXP, Industry Nine, or Aviee Hubs. Please reach out to customer service at 1(800) 682-0570 to find availability. We can special order custom wheels with extra lead time. Prices may vary depending on the hub selected in the event of a special order. Product image is an example of wheel profile only, actual product will have brake tracks.
