The 72mm Nineballs from Sector 9 are a very unique offering. This wheel is intended for use as either a great cruising or carving wheel, or a thane dumping freeride wheel. They feature a consistent and controllable sugary urethane with a square lip shape. This wheel would fall into the fun freeride, or tech freeride category of wheels for its corner taking abilities, but fun and easy sliding nature. These properties also make it great for hard carving fun and cruising. The 72mm shape will roll over large cracks and rocks, while the 75a soft durometer urethane will keep the ride plush and comfortable.
