With a soft durometer for grip and a thick, square lip these 74mm Nineballs are designed to keep you locked-in around corners. Plus, the Nineball formula is a super high quality urethane that is preferred by many of Sector 9's team riders for downhill action.

Ride Style

Downhill - To go fast and stay in control, you want a big wheel with a lot of contact with the pavement.

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

Square Lip - The most grip allowing you to carve deeper and take tight lines around corners without worrying about losing traction.

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.


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 74mm Nineball Longboard Wheels
the wheel shown here is a great ride for your money I would have to say. They roll over almost any rock/pebble. I used them for downhill and they worked awesome! Good buy. I would get them again
