Bones SPF Ripples P5 Sidecut Wheels
About Skate Park Formula
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:
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.
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.

About Bones Wheels
Product Performance: Many skaters assume the performance and quality of skate wheels are all the same. A wheel is a wheel is a wheel, they might often say. That's actually not the case. In fact, very large differences exist between the raw materials, manufacturing process, quality control and performance of different wheel brands. Up until now though, a wheel's reputation has been a combination of market hype, market muscle, skater support and word of mouth. Bones wheels popularity is largely a result of superior quality, performance and durability.
Real Value: BONES may not be the lowest-priced wheel, but our abrasion test chart shows why Bones is the best value. After all, what good is a cheaper wheel if it flat spots the first day? BONES wheels offer the best combination of product performance, durability, quality, and customer service available today. In other words, you might be able to find a lower price, but never a better value.
Our Strength: All BONES WHEEL unique formulas are solely developed and produced in our own manufacturing plant located in Santa Barbara, CA. Using drastically different physical and engineering properties for each formula, BONES creates unique urethanes for specific applications of skateboarding.
