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 Wheels

Sector 9 61mm Nineballs Longboard Wheels - blue (78a)
These wheels roll through and over anything. I have an old Cab deck that still had some life left in it. Mounted these up specifically to skate those chunky street spots where hard wheels simply wont work. These wheels allow you to be creative on where your able to skate. Let's face it, that's what it's all about!

These wheels are a great size, soft enough to roll over awful pavement, and the stone ground finish is great. Got these for 10% off so the price couldn’t be beat either

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.

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
