They call them Butterballs for a reason.
The Sector 9 Butterballs are poured from only the finest thane for all the sideways, 360, spin like a fairy freeride downhill maneuvers you can dish out. Consistent, predictably long slides make for a crowd favorite on any hill. The centerset core makes it so the wheel wears evenly as you kick out massive slides.
Now with Sector 9’s patented core, the Sector 9 Butterballs Cosmic Core allow more urethane support. Your slides will be longer, your wheels will last longer with more flatspot resistance, and your speed will be much speedier!
