Powerflex Gumball Wheels - White/Black 58mm 83b (Set of 4)
Powerflex Gumball Core wheels are perfect for street skating, skateparks, backyard pools and DIY spots. Powerflex's custom 83b Hard/Fast Anti Flatspot Formula is the perfect mix of slide and grip. They let loose to slide, but don't slip out when you don't want them to. They are stone ground and ready to ride - no break in period required.
Powerflex's Gumball Cores are just what they sound ike, sweet and colorful... but it doesn't end there! What makes these wheels perfect is the 55d core that allows a perfect spin, but absorbs more shock than any single pour 83b/101a wheel ever could.

About Durometer B Scale
Shore Durometer A Scale is good, but does not cover the entire range of skate wheel hardness and is very limited because the scale goes from 1 to 100 and anything over A 95A does not compute accurately.
Shore Durometer B Scale is perfect for skate wheels because:
- It is very similar to the A Scale, but reads 20 points lower, allowing the useful scale to be extended by 20 points, which covers the entire hardness range of skate wheels in one scale. It uses the same soft spring as the A Gauge, but the conical gauge needle of the D Scale.
- Because the spring is soft, the B Scale gauge needle does not puncture the skin of the wheel surface, resulting in the same reliable reading as the A Scale does.
