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

Smooth - The natural shiny finish provides extra grip for railing corners and is more responsive when pumping/carving compared to wheels with a stone ground finish.

Wheel Features

Top Shelf Formula - Sector 9's premium quality Urethane formula that provides you with an ultra-smooth and evenly wearing wheel to keep you rolling for years to come.

Cosmic Core - The Cosmic core increases roll speed and provides better control through slides.


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.
