What's the hardness rating mean?
Sure-Grip Uses the "A" rating when giving a wheel its hardness rating. Their are several different ways to measure the hardness of a material, 12 in fact. The most common are "A" and "D." "A" is used for softer materian and "D" for harder material. In roller skating the higher the number the harder the wheel. Outdoor wheels typically are between 78A - 88A, indoor wheels are typically between 90A - 100A.

What type of material are your wheels made out of?
We use a material called Poly BD in our Fugitive, Power, Power Plus, and Interceptor wheels; its a material that was developed 20 years ago but just seems to work the best in roller skating. Its a material that has high rebound, good grip and good wear. Their are two easy ways to tell if a wheel is truly made from Poly BD. One, the material has a distinct smell, in a way it smells bad. Two, tiny bubbles or holes will appear throghout the wheel.

Whats the hardness of my wheels?
Sure-Grip offers many different types of wheels, each was manufactured for a specific purpose. With this in mind it is important to note that the hardenss number alone does not necessarially mean that the wheel will be that soft or that hard. but to answer the question; Fugitive wheels:
Black, Blue, Pink, and Red are 92A; Purple is 94A; Green is 96A.
Interceptor:
Black, Pink, Blue, Red, Yellow are 93A: Purple, Green are 97A
Power Plus:
Same as Interceptor

Whats the difference between the metal hub and plactic hub?
Sure-Grip offers 3 wheels that feature an alumnium hub, they are the Power, Power Plus, and the Interceptor. All our other wheels feature a nylon hub. The difference is simple, one is harder than the other, which will in turn make the wheel itself feel harder. A wheel that is 95A will feel harder on an alumnium hub than on a nylon hub.

What wheel should I use for Roller Derby?
The wheel of choice in Roller Derby is the Fugitive wheel. The smaller nylond hub allows for more urathane to be poured around the hub, thus giveing a softer feel. Among skaters the color of choice is the Blue Fugitive which is the softer of the colors.

What wheel should I use for Jam Skating?
Jam Skating, due to the type of skating that is being done we reccomend using our Sure-Grip Power wheel. The alumnium hub offers the strength needed while being light weight. Utilizing a small core design allows for more ureathane to be poured around the core which will absorbe the forces associated with Jam Skating. A Power Plus or Interceptor wheel is not reccomended, that wheel was designed for speed skating only.
