Sector 9 Nineballs

With a 78A durometer, these wheels are quite soft, which makes them excellent at absorbing road vibration. They will roll over rough surfaces much more smoothly than harder street wheels, providing a comfortable, dampened ride.

At 70mm, these are relatively large wheels. While they fit most longboards, you may experience 'wheel bite'—where the wheel touches the deck during sharp turns—if you have a standard popsicle-shape skateboard or a deck without wheel wells. They are best suited for longboard or cruiser setups.

While they are primarily designed for cruising and commuting, the 78A durometer offers a predictable grip. You can initiate small slides, but they are not specialized 'slide wheels' and will feel grippier than harder, stone-ground options.

The larger 70mm diameter helps you maintain momentum, meaning you won't have to push as often to keep your speed up. It also allows the wheels to roll over small rocks and debris more easily than smaller, harder wheels.

No, these wheels are compatible with standard skateboard bearings. If your current bearings are still spinning freely and are free of grit, you can simply swap them over to your new wheels.
