WUR Hybrid ceramic bearings
WUR have been making skates for the biggest skating brand in the world for years and now they have launched their own brand world wide.
Their hybrid ceramic bearing contains ceramic balls to ensure a more perfect shape with a nylon runner and steel outer. This combination keeps your ball bearing in a shape that it can run faster and with less friction for longer, while keeping the price lower than others.
The Hybrid Ceramic bearing comes in a metal case so that you can keep them organised when you're not using them.
