 CHris King 6-bolt vs Centerlock Comparison

Engineered and assembled in Portland, OR, 6-bolt Chris King mountain hubs feature the same precision manufacturing and robust feature set of past models. 72 points of simultaneous engagement are delivered via Chris King’s patented RingDrive system and can handle an industry leading torque load of 800 ft/lbs. Bearings are purpose-built for optimal performance for the lifetime of the hub and are also user-serviceable without the need for special tools.



Chris King front hubs remain similar to the previous 6-bolt model and still feature heavy duty bearing seals and precision manufactured internals to keep mud and water from getting into the hub shell.

Both front and rear hubs continue to utlize a one-piece solid axle without endcaps to ensure the stiffest possible interface with your bike frame.



The 6-bolt hubs utilize the exact same axle and freehub (drivers) that the centerlock boost hubs use. Because the disc rear bearing is larger in diameter, the 6-bolt hub uses an oversized tension collar for compatibility with the axle system. The RingDrive engagement mechanism lives inside of the hubshell which provides additional protection from the elements and allows it to have more contact area than would be possible with a traditional freehub design. This provides a solid pedalling platform and ultra efficient performance on the trails.
