How many packs do I need?
Each pack has 4 wheels, enough for one skate. A pair of quad skates takes 8 wheels, so order 2 packs. Set the number in the Quantity box.
Which floors is it for?
Atom's wheel chart puts the 93A Savant on sport court and slick floors for skaters 126 pounds and up, and on coated, grippy floors for skaters under 140 pounds.
Which hardness should I pick?
The Savant comes in six hardnesses, one color each. The 88A is pink, the 91A blue, the 93A purple, the 95A black, the 97A orange and the 99A green. The lower the number, the softer the wheel and the more it grips. Atom's wheel chart puts the harder ones on coated, grippy floors and under heavier skaters.
