The Helo ABEC 9 Bearings were built for the competitive skater chasing top-end performance without breaking the bank. Pre-lubricated with Helo Light Speed Grease, they're ready to roll right out of the box with smooth performance. Inside, a nylon bearing cage reduces friction and weight, helping to maximize spin and consistency through every stride. Plus, the removable backplates make them fully serviceable, so you can keep them clean and running longer.
