SUPERSTREET MYSTERY WHEEL.
Joycult wheels are handmade in Brantford Ontario Canada by Matt Watkinson. From face to bearing, duro to duro, Joycult wheels are designed to handle all terrains.
Durometer is a rating system for which hardness is determined. The higher the number, the harder the "thane"70D is harder, a bit more responsive and designed for sliding more efficiently on rough terrain.60D is the softer of the two, but, I wouldn't call them soft by any means. They a are slightly more grippy and although they will perform well on rough surfaces too, these were designed with smooth surfaces in mind.
Carefully formulated and perfected to create a truly unique feeling under your fingers.
