The patented RingDrive™ engagement mechanism has made the Chris King BMX hub the hub to beat at tracks all over the world. With 72 pedal positions per rotation you'll always have a choice of the perfect start. The positive, rapid engagement transfers your power instantly to the rear wheel, giving you the confidence you need to win. Now all you have to do is choose which color it is you want to be seen with on the podium.

The BMX driveshell rides on a premium quality needle bearing which turns directly on our super-heavy duty steel rear axle. The rear axle has threaded aluminum inserts that are easy to replace in case your threads get messed up, WITHOUT throwing away the axle. This hub is built to last a lifetime. Consider it an investment in your lifelong passion for BMX.

All of our rear hubs utilize our patented RingDrive™ engagement mechanism. RingDrive™ uses 72 engagement teeth on each drive ring. That means the hub engages over 3 times quicker than the standard 24 tooth pawl-type freehub. Trying to get started again in the middle of a steep uphill section? Going for the surprise jump to drop your buddies? This unique design offers instant and positive engagement that's capable of handling a torque load of over 800ft/lbs, or over three times more than most other high end hubs we've tested. It is the heart of our hub and all the rest is built around it
