Ride Style

Carving/Cruising - Carving/cruising wheels meet the needs of many different skate disciplines but generally, have a good roll speed and are soft enough to handle craggy streets riddled with cracks and rocks.

Core Placement

Centerset - The hubs in these wheels are set equidistant from the lips, resulting in an even wear and a controlled slide.

Word to the wise: They can be rotated (like your car's tires) to promote even wear and a longer lifespan.

Wheel Edge

Round Lip - Breaks traction more easily and offers smoother transitions from grip to slide. Round lip wheels are generally preferred for freeriding.

Surface Type

Stone Ground - Perfect for freeride. With zero break-in needed, stone ground wheels slide much easier than smooth wheels, right out of the cellophane.

Wheel Features

9-Ball Formula - Sector 9's standard formula urethane, perfect for all-around cruising or ripping.


78a - The most common durometer we see amongst cruiser wheels. They have great grip for cornering and easily roll over cracks, small rocks and the like.

Sector 9 61mm Nineballs Longboard Wheels - white (78a)
The wheels are great. They are soft enough to cruise around on and have great grip. If you are trying to slide with your board they might need some wear before

It is great product, but what I got does not have the same graphic that I expected.
