What does it mean when roller blades say 88A?

88A refers to the Durometer, or the hardness of the wheel, not the wheel size (mm)- . The harder the wheel, the longer lasting it will be. The downside- less shock absorption. Rated on a scale of 1-100, the most common being in the 78-82 range. 88A should hold up well on rougher surfaces such as roadway. If you're blading indoors, a lower Durometer might be a better choice.

Will, you contradict yourself. San is right, the A designates the hardness of the wheel, with 88A being a pretty hard wheel. It will have less grip but more durability.





If your wheels are an 88A, I hope you aren't using them indoors, because it would be very difficult to find the proper grip. I used 82A wheels once indoors and couldn't skate worth beans because it was too hard for the surface.
Reply:It refers to the wheel size.





Wheel sizes vary depending on the skating style:





48-60 mm for aggressive skating.


68-72 mm for artistic inline skating.


72-80 mm for general recreational skating.


59-80 mm for roller hockey skating and slalom.


80-110 mm for speed skating.





In general the bigger the wheel, the faster the skate. However, large wheels take more energy to start rolling. Smaller wheels allow faster acceleration, maneuverability, and a lower center of gravity. Wheel hardness is measured on the A scale (see Durometer) and usually ranges between 78A-93A (higher numbers are harder). Harder wheels are faster and more durable, but soft wheels may have better grip (grip is determined by many factors, and wheel manufacture is arguably more important than durometer) and less affected by road bumps. Wheel profiles and thicknesses again vary by application. Elliptic profiles minimise friction for a faster ride; more rounded profiles have better grip and are more stable.
