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.

Perfect Popsicle Cruiser wheel

Sector 9 61mm Nineballs Longboard Wheels - smoke (78a)
I put on 2x 1/8" risers to an old 8.25" deck and this thing flies around the neighborhood, annihilates cracks and cobble, and still cracks a nice ollie onto or off a curb.

I've skated other "filmer" wheels with 85a to 92a duro. No reason to ever go in between unless you are actually filming. Softer wheels are best for cruising, and have a 99a+ duro set-up for street/park.

Sector 9 61mm Nineballs Longboard Wheels - blue (78a)
I haven’t skated long on these but they’re a nice cruiser wheel. The wheels are way darker than pictured is the only thing I have to say that isn’t completely positive

Sector 9 61mm Nineballs Longboard Wheels - green (78a)
while these wheels are 1mm smaller than my other wheels but the softness is excellent for just cruising around the streets. These have done very well on sidewalks and roadways.
