Skatepark Formula™ (SPF) is very high quality urethane specifically formulated to resist  flatspotting on slick or smooth surfaces while maintaining a higher  rebound for a quicker response and a faster roll.

Skatepark Formula™ has a high resistance to abrasion while not  compromising hardness and slide ability. Simply put… Skatepark Formula  wheels grip better on slick surfaces, are almost impossible to flatspot,  and are the fastest, longest lasting wheel on the market today.

You won’t find our Skatepark Formula from any other wheel supplier so  get a set and find out for yourself what the word on SPF is all about.

         

About DUROMETER B SCALE

               

Shore Durometer A Scale is good, but it 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:

  1. 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.
  2. 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.

 

Shore Durometer D Scale is designed for hard rubbers and rock hard  urethanes, not soft, bouncy urethanes that are used in skate wheels. It  has a very stiff spring behind its sharp conical needle and often  punctures the skin of the wheel being measured, this resulting in 5-10  points softer reading than is correct. Thus, Shore D Scale should not be  used for wheels in the useful skate wheel range.
