The Professional (Animals) Wheels are the Tightest of the hi-end Professional FreeStyle Wheels available from Roll-Line today and this series is probably Skated on, Jumped on, and Spun on by more National and World Champions than any other FreeStyle series of wheels. Roll-Line has developed this wheel giving it properties that withstand the extreme abuse a FreeStyle skater can dish out. The Roll-Line Professional is a Lo- Profile, very durable wheel which has incorporated a Hub which is Strong, 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 very Tight Grip, while providing great ROLL. The hub color identifies which hardness the wheel is.
Green Hub: 92A.
White Hub: 95A.
Gray Hub: 97A.
Yellow Hub: 99A.
