The North Fullcore wheels are back and boy do they look good! This version of the Fullcore wheels are 110mm in diameter, and 24mm in width. This size is the industry standard so they'll fit almost every fork/deck out there. The Fullcore wheels come with an 88a durometer which is on the softer side of the spectrum. Softer wheels will absorb more impact, feel smoother, and will grip better in smoother terrain (such as your local skatepark). North supports all their wheels with a lifetime warranty that covers chunks, and de-hubs.
