Sector 9 is bringing you the best of both worlds with this sweet, downhill-freeride hybrid wheel. The 73mm Sector 9 race formula wheel features a wide contact patch that will keep you gripping through the corners but has rounded lips to make pushing out slides a breeze. Due to its center set core, these wheels can be flipped if they start to cone. No more throwing out wheels early! You can expect these wheels to wear evenly all the way down to the core.

If you want a little more resistance in your slides and extra grip in the corners, go with the yellow 78a formula. If you want your slides to go on for days or you like a hard, fast rolling wheel, check out the 82a formula. If you want the best of both worlds, or you really like the color blue, the 80a's are for you!

Make sure you've got plenty of wheel clearance before you hop on your board!! These center set wheels will be more prone to cause wheelbite than a normal 70mm offset wheel!

Sector 9's Description

Sector 9 says:
In racing wheels, chemistry isn't just important, it's everything. And you cannot just dump a bunch of compounds into a mold and call it good. You have to do things exactly right so the mixture "goes off" the way it is supposed to.
At Sector 9, we have been working with top notch chemists to ensure that our new Race Formula Nineballs have superior rebound and grip. The net results feels like you've got fire under your feet.

Super Long Lasting!

I rode these wheels since May of 2015 and there is still many slides left to do on them! I learned many things that I could have never imagined myself learning when I first started, on these wheels. Basically, if you are looking for a good pair of wheels that do not flat spot easily and last for months of hard riding, these are for you.
