Zealous Ceramic Built-In Bearings - White Helmets O Matter stress-resistant frame materialZealous Bearings are one of the most popular bearings in the industry. With built in speed rings, and spacers at a precise . 4045" these bearings eliminate all slop in your wheels for smooth rolling and predictable slides. They're lubed with nanoceramic grease that finds all of the small dings in the ball bearings, fills them in, and corrects the bearings for a frictionless roll. This equates to a fast, smooth, and long lasting, self fixing bearing.
