A ball of butter can be slippery, that's why the Butterball wheels from Sector 9 make the perfect slide wheels.

Freeride - Wanna get sideways? If "drifting, heel side standies, pendulums, and Coleman" are part of your vocabulary you're in the right place. For freeride wheels; a smaller contact patch, a stone ground finish, and rounded lip all help them slide easily, right out of the box.

A word to the wise: if you are just getting into freeride try out a smaller size wheel (think 60mm-65mm) with a harder durometer (82a or harder) because it will be easier to break away into a slide, making it easier to practice. Practice slides with friends and try different setups. Will you flat spot your first set of freeride wheels before coring them? Yes. Will they wear unevenly and leave you with a couple bruises? Absolutely. But, it gives you a whole new look at the hills, a whole new freedom. The great Cliff Coleman (father of downhill slide) says, “If you can crouch down and ride a skateboard, then you can learn this slide" as he talks about the classic Coleman slide.

As you gain experience, and speed, you'll find bigger wheels can be better because they will last longer and will be faster on the hill. Different durometers, center-set vs side-set or offset cores, and different urethane formulas will help in different weather/road conditions so make sure you experiment to find your favorites.

Freeride takes you to a new level of skating. Simply put, it's groundbreaking.


80a - Soft with plenty of grip. You'll be able to smoothly roll over rough surfaces without getting hung-up on cracks or small rocks. These wheels are slightly harder than the standard 78a and are easier to initiate into slides and drifts. They offer great slide control and are more durable, but won't slow you down as quickly as 78a wheels. Ideal for cruising, carving, freeride, and downhill. Also a good filming duro as its a bit faster than some of the softer varieties.

Urethane skate wheels generally range from 75a-101a, the numbers increase with the hardness of the wheel.

Core Placement

Centerset - Centerset wheels have cores that are placed directly in the center of the wheel, equidistant to the outer edge of each lip. This core placement style gives the most amount of grip because it creates a very large inner lip.

Another advantage of centerset wheels is that they can be flipped inside out to promote even wear and a longer lifespan. For this reason, many freeride wheels have centerset cores paired with small contact patches and round lips.

Wheel Edge

Round Lip - Rounded lips allow the wheel to break traction more easily and offer smoother transitions from grip to slide. Round lip wheels are generally preferred for freeriding.

Surface Type

Stone Ground - Stone ground wheels slide much easier than smooth wheels right out of the box. Stone ground wheels don't have an initial break-in period like smooth wheels, and offer predictable slides without having to wear down the wheel surface.

Wheel Features

Slide Formula - These wheels have been specially formulated to allow for the maximum amount of smooth, chatter free slide.

Center Set Hubs - Center Set Hubs means that the hubs in these wheels are set equidistant from the lips, this results in an even wear and a controlled slide.

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

These wheels are perfect for sliding. They are super predictable. They leave some pretty nice thane lines, but they are hard to cone.

A Great Combination

Sector 9 Butterball Slide Formula Longboard Wheels - white (80a)
I bought the Sector 9 Butterball Wheel, Bacon Bits hardware, Bones bearings, Gulwing Charger II trucks and a Jessup sheet. The combination is an almost frictionless, smooth ride.

Sector 9 Butterball Slide Formula Longboard Wheels - white (80a)
Sector 9 hit the jackpot with these wheels. Being 80a the butterballs aren't too soft or too hard. The Butterballs have a nice smooth quiet slide to them. When sliding the Butterballs are not choppy or loud with friction resistance. The Butterballs leave thane on almost every single surface in my town. The only cons i saw with the Butterballs is that they wear pretty fast, also when you are near the core they began to chunk. But all in all i would buy these again and again.

Asked by Jordan on 4/12/2017
How is the new 75a formula?
Answered by Graig A (Tactics Employee) on 4/19/2017
They are going to give you a similar feel and slide to the 80s but just have that extra grip for when you are really needing a speed check or take a corner and not slide
