The Speedrings skate wheels from Ricta have the speed of cored wheels without the hard chatter, plus they don't squish out on landings like non-cored wheels. Roll faster and roll away from more tricks!
So this is a dual hardness cored wheel. The idea is that the softer core will give you a smoother ride with less chatter while maintaining the speed and slide with the 81b outer surface. I'd say it works. Nice and fast with a good slide. Comparable to newer OJ wheels. Oh and the soft core, that's kinda weird. Makes your board sound like you have soft wheels. Like a crusier wheel. Pretty trippy. Not perfect but real good.
