Santa Cruz Slime Balls Brains Skateboard Wheels

With a 99A durometer, these wheels are versatile enough for both. They are hard enough to slide easily on smooth park concrete while maintaining enough grip for technical street tricks.

A 54mm diameter is a standard, all-around size that works well with most street and park setups. If you are currently riding very large cruiser wheels, you might need to adjust your truck height or hardware, but for most standard skateboards, this is a direct fit.

These wheels are engineered for durability and resistance to flat spots. While no urethane wheel is completely immune to flat spotting if you are consistently powersliding on rough surfaces, the 99A hardness rating is specifically chosen to withstand the friction of technical tricks.

You can expect a fast, responsive ride. Because they are on the harder side, they will feel snappy and provide excellent feedback on smooth surfaces, though you will feel more vibration on rough asphalt compared to softer cruiser wheels.

Like most printed skateboard graphics, the swirl design will begin to fade or scuff as you skate and perform tricks. The graphic is primarily for aesthetics, and the performance of the urethane remains consistent regardless of the print's condition.
