Sector 9 Race Formula Yellow Wheels - 74mm/78A

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.
