Powerflex Gumball™ Core wheels are perfect for street skating, skateparks, backyard pools and DIY spots. Our Custom 83B Hard/Fast Anti Flatspot Formula is the perfect mix of slide and grip. They let loose to slide, but don’t slip out when you don’t want them to. They are Stone Ground and ready to ride no break in period required. Our Gumball™ Cores are just what they sound like, Sweet and Colorful…. but it doesn’t end there! What makes these wheels perfect is the 55D core that allows a perfect spin, but absorbs more shock than any single pour 83B/101A wheel ever could. Instead of printing graphics that scratch off in 5 minutes, our name and reputation are engraved in every set. Our connection doesn’t end when the graphics are scratched off, we are with you forever, proudly.
