Z-Flex is introducing our updated Z-Pro wheel. Available in 8 different colors, these pink Z-Flex wheels are designed for a quick, yet smooth ride. The Z-Pro's are 60mm and 90A in durometer, which are great for any cruiser. At 90A, they are a little harder than our Z-Smooth, but still great on concrete, asphalt, or wood. Pair them up with our Z-Speed Bearings and you'll be ready to hit the streets!
