Santa Cruz Slime Balls Speed Balls Wheels

With a 99A durometer, these wheels are designed to be versatile. They are hard enough to slide easily on smooth park concrete but offer enough grip for technical street skating on rougher asphalt.

The 53mm diameter is a standard, all-around size. It strikes a balance between acceleration and top speed, making it a reliable choice for most skaters regardless of their preferred terrain.

These wheels are built with durable, high-quality urethane designed to resist flat spots. While no wheel is completely immune to damage from heavy power sliding, this construction is engineered to withstand daily abuse.

No, these wheels are compatible with all standard skateboard bearings. You can use your existing set or install a new pair without any special modifications.

Unlike soft cruiser wheels that absorb vibration and grip the ground tightly, these 99A wheels are hard and responsive. They are built for tricks, slides, and precision rather than just rolling over rough surfaces comfortably.
