The Skater Barcelona Wheels with Aluminum Inserts are built for speed, control, and durability. Measuring 62mm x 30mm with a 92A hardness, they’re designed for high-performance skating on smooth surfaces. The aluminum inserts help dissipate heat from the bearings, resulting in a smoother roll and increased speed. Made from durable urethane, they also allow for precise, controlled stops. Available in black with your choice of red or blue inserts—or mix and match—for $99.
