The updated Z-Smooth wheels are insanely fun! The 63mm 83A wheels can fit cruisers, longboards, and even our mini pintails. A little softer and slightly larger than our Z-Pro wheels, the Z-Smooth are great all around wheels for tons of different set ups. The Z-Smooth are available in 11 different colors, including 6 different transparent colors that you can see through. Pop in some of our Z-Speed bearings and you're good to go!
