Grit 4540 - White Industries Hubs

GRIT 4540 Wheelset

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 optimised 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 tyre bed. By removing holes from the tyre bed, the wheel becomes incredibly stiff (holes+carbon aren’t best friends). That allowed us to make the tyre bed thinner (lighter) while providing greater hoop stiffness (stronger). Oh yeah, no more tubeless tape either (you're welcome).

Tubeless and podium ready. Reserved for those with GRIT.
