Questions
How many do I need?
A pair of quad skates takes 8 wheels, so 2 packs. One pack of 4 fits a skateboard.
Will it fit my skates?
Anabolix says the Catapult fits a quad skate or a skateboard and needs no special plate.
Yes. The higher the number, the harder the wheel. A harder wheel gives more roll and slide and less grip. For pavement and sidewalks, the softer Anabolix Triumph 78A gives a smoother ride.
