Uhh Ohh, what has Sector 9 done this time?! Sector 9 is back with their RFW in a special new Race Formula. The rounded lips on this wheel mixed in with the fast urethane results in a smooth sliding and fast rolling wheel. If you are looking for a great all around wheel then look no further.

The buttery slides and grip mixture of this wheel is unsurpassed! Of course the rounded lips will allow for a bit more slide. Pick up the 78a duro for a plush ride with shorter slides or pick up the 82a duro for you free-ride phenoms!

Put these longboard wheels on your downhill and free-ride board for a great time!!! Add these 70mm Race Formulas to your pavement thrashing arsenal!

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.

Almost had to steal these from my friend because they carried a calm eminence like a cat does when its sitting on the top of the chair above you head. The cat seems to say in a cool whisper "hey, you should take me to your favorite downhill spot and grind me into the pavement until we're good friends"

My favorite wheels. I'm sure I'll pick up another pair once mine are done. They are predictable, quiet, and fast. I weigh 165 lbs and I think the 80a is perfect. Great combination of grip and slip.
Nice and smooth
