The Princeton GRIT 4540 was designed from the ground up to re-calibrate your expectations from an all-road carbon wheel set. The are lightweight, amazing stiff and versatile. Always snappy, fast and stable.
These wheels are ideal for climbing and all purpose road OR gravel/CX (mixed terrain, gravel, cyclocross).
Princeton achieved all this taking their experience from the model 6560, which was a wheel successfully used by the Team Ineos during the 2021 Tour de France and a big part of the season.
The GRIT wheel has Princeton patented variable depth sinusoidal cross section, for unrivaled cross wind stability. The wheel also has 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. The rims also feature a uniform, hole-less tire bed. By removing holes from the tire bed, the wheel becomes incredibly stiff (holes+carbon aren’t best friends). No holes in the carbon bed also allows to make the tire bed thinner (lighter) while providing greater hoop stiffness (stronger). All these equals to no more tubeless tape either.
The GRIT 4540 comes in tubeless/tube and tubular versions. You are buying a clincher XDR version on our web site. The Shimano version is on the picture.
