Roll-Line Formula Ultra-Tight Professional Dance Wheels

The Formula Wheels continue the Grease line of wheels (just 1mm smaller in diameter) , with the absolute MOST GRIP specifically designed for Hardball Hockey, Roller Derby, JAM Skating, and is the all round best JAM, Skate, & Party Wheels available today. Roll-Line has reinvented the wheel giving it properties that are normally not achievable in the one wheel, Tight Grip and Super Roll. Roll-Line based the design on that of the Low Rider Tire concept. Large Hub and a Smaller, Thinner Tread, and produced one of the LIGHTEST, TIGHTEST, and BEST ROLLING wheels available. Roll-Line has developed the Hub which is incredibly Strong, very Light, and with extremely Close Tolerances for Roundness, Trueness, and for the Cage where the Bearings and Spacers are mounted. The Roll-Line Tread is a Cast Urethane BiCompound Formula, which provides Tight Grip, without the tire compression that is normally associated with a wheel this tight. The lack of tire compression, along with the thinner tread, mounted on the Roll-Line Hub, is what provides the INCREDIBLE ROLL. The Formula 88A (maximum grip, but still with great ROLL) is for skating surfaces with very little grip. The outside face of the Hubs on the Formula are Silver Chromed, while the color of the back side of the hub is White and identifies which hardness the wheel, which is 88A.
