Balls of butter, indeed! Sector 9 has crafted a lovely urethane composed of the finest urethane for performing all of your favorite downhill skateboarding acrobatic maneuvers and poured it into a shape that not only compliments the slide, but enhances it!

The Sector 9 Butterballs Shred Thane Formula Freeride Wheels are centerset, relatively wide and ideal for busting mega-sized standup slides, hands down slides, sit down slides, or whatever other slides the kids are doing these days.

Sector 9's Butterballs Wheels come in 65mm and 70mm to give you two less excuses for not being able to do that Switch Toeside... Does that mean you'll be throwing switch toesides into hairpins at the local beach access road like Duke Degen? Maybe. Probably not... But you can certainly get there someday! The only thing that could make these wheels even better is if you painted a Lobster on your deck.

Sector 9's Description

Butterballs are the original Sector 9 Shredthane wheel. A center set supportive core helps you in rotating the wheels to keep them wearing evenly as you shred them into oblivion and leave thane trails all over your favorite hill.

Butterballs are really good. They leave thane (which I love) and they are fairly inexpensive. Do be careful and rotate your wheels or they could cone, or wear unevenly.

Ive had these for a while, came on my sector 9 dropper and mini daisy, and once you break them in they have a nice buttery slide with nice slide and hookup. Does not thane as much as i expected, but thanes a good bit.
