Why We Like The GRIT 4540 Tune Disc Brake Wheelset

Finding a wheelset that can be used for several disciplines is like coming across a pot of gold at the end of a rainbow. Princeton CarbonWorks fills their pot of gold with the GRIT 4540 Tune Disc Brake Wheelset, a wheel designed for all-road use, from gravel trails to the road and even through your favorite cyclocross course. The combination of the TUNE hub with centerlock disc brakes allows for a quick, smooth stop. The GRIT 4540 is lightweight, stiff, fast, stable, and snappy, combining to create the perfect combination of elements we like in a wheelset.

A re-engineered nipple bed provides a thicker area of carbon in more necessary areas while removing material in the areas where it is not needed. The tire bed features a design with no holes in the tire bed, improving the stiffness of the wheel and allowing the tire bed to be thinner and lighter. The GRIT 4540 is also constructed with a variable depth sinusoidal cross section that offers unrivaled crosswind stability, ensuring you have full control no matter how windy the conditions.
