Bones Skatepark Formula™ (SPF) Sidecut Wheels - 60mm 101A

101A in Skatepark Formula. At this hardness, the wheel still has grip, which solves the problem for those who skate on polished concrete, those old parks where the floor is already shiny and hard wheels slip mid-turn. Here, you plant your foot and it holds.

60mm diameter by 34mm width. A large wheel, made for bowls, pools, and long transition lines. It covers more ground per rotation and maintains speed without you having to push between obstacles.

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 SPF was developed for concrete, which heats up urethane and wears it down quickly. This one holds up without getting flat spots.
