Dragon BUILT Bearings are designed from the ground up for skateboarding and longboarding. Unlike other bearings on the market, Dragons’ offer signature Labyrinth shields to help prevent dirt and debris from getting inside the bearing, drastically improving overall performance and life of your bearings. They come with a lifetime warranty on the entire range! These super durable bearings are lubricated with a signature grease formula to ensure that the weather doesn’t ruin your skate session. They have been tested for countless months in the South Bay of California and they have proven to hold up in salty, ocean air, wet conditions, through sand, and held their tight tolerances through the chunder riddled roads of Malibu. They have also been tested at numerous races, slide jams, during free ride sessions, downhill runs, park sessions, street sessions, cruising and dancing, and perform at their peak, even months after installation. Each bearing is double sealed with extremely tight non-contact labyrinth seals to prevent dirt and gunk from hindering performance.
