Sector 9 Wheel 75A Butterballs

Butterballs 70mm are the original Sector9 Shredthane wheels. A Cosmic Core center helps you spin the wheels so they wear evenly as you shave them and leave thane marks all over your favorite hill.
This light-colored version has a gorgeous look and a softer durometer. The 75a urethane blend will give you a smooth glide.

ABOUT THE CORE

Core technology has come a long way and is one of the final frontiers in the progression of the modern skateboard wheel. Many possibilities for wheel shapes and urethane blends have been developed, but the inner world of the core has remained largely unexplored. We finally decided to design our own core, and the list of benefits is just the beginning: from increased rolling speed to better-controlled glides.

ABOUT URETHANE

If the average driver really knew what our wheels went through to get to our range, they might feel more comfortable fitting them to their car. On a more serious note, these wheels are thoroughly tested before they even become prototypes.
Then we dissect them, test them, rework them and test them again. This process often seems tedious, but it has proved fruitful time and again. Whether it's our Race Formula, our Shredthane or our Nineballs, these wheels all stand up to the rigors of the road and perform when you need them most.
