MOTION NOTE: Whether downhill or freeriding is your game, the Race Formula from Sector 9 will perform excellently in either category. The
69mm Offset features a medium sized contact patch with a sharp square lip on the outside and a sharp 90˚ degree edge on the inside. What this means is that this wheel will grip harder than most other wheels this size but still break into a slide easily. Because the outside lip is not that thick it bends easier, requiring you to put in less effort to slide. On the flip side, the sharp inner lip gives you a great amount of grip straight out of the box. The Race Formula Urethane is very durable, ensuring these wheels will outlast most others. All duros of these wheels are great for freeriding but for downhill we recommend the 78a (yellow).

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.
