Bones Skatepark Formula™ (SPF) Sidecut Wheels - 54mm 101A

54mm by 31mm wide, in 101A. This is the wheel for those who spend their afternoon at the park without being able to decide: half an hour in the bowl, half an hour trying tricks on flat ground. Low enough for the skateboard to be responsive, hard enough to ride fast.

At 101A, the urethane still has some life. That counts on polished concrete, in those old parks where the floor already shines and a harder wheel slides when you put your foot down. Here, it grips.

The hardness is written in two ways on the spec sheet, 81B and 101A. It is the same value. Bones measures hard wheels on the B scale, twenty points below the A scale.

The Skatepark Formula was made with concrete in mind, which heats up urethane and eats it quickly. This one holds up without getting flat spots.
