The Easy People Longboard Bearings are a small but essential part of any Complete Longboard. They help determine how long a push will keep the wheels propelling, they are made with tiny steel balls inside. They come in various grades, ABEC-5, ABEC-7, and ABEC-9. Each level of bearing is tuned for the grade of the rider, from beginner to advance. Bearings also help your ride be smoother, so you don’t get caught by small cracks or rocks.
