GripLock™ - The Next Generation In Chris King Headset Technology

In 1976 Chris King manufactured the first Chris King headset. It was built to medical grade tolerances and set the standard for what a quality bicycle component should be. Since that time bicycles have changed significantly,from 6-speed road bikes and 45-pound fully ridged mountain bikes to sub 10-pound road bikes and 35-pound dowhnill bikes, the design of today’s modern bicycles has kept pace with the development and style of riders. As riders we want our bikes to perform with out hassle so we can get the most out of our riding experience and it was with an eye on the changes in capabilities and material of todays most advanced bicycles that we developed GripLock™ the next generation of our legendary headsets.
Chris King’s GripLock™ headset retention device uses an isolated wedge system to separate headset bearing adjustment from steerer tube location thus eliminating loose headsets on long travel mountain bikes while simultaneously removing any chance of headset inflicted fatigue on the lightweight carbon steerer tubes found on modern road forks.

This is accomplished by isolating the thrust force that passes through the steerer tube from the bearing race that provides the radial force that preloads the headset bearing adjustment. In standard headset systems this preloading wedge is affected by each impact that runs through the steerer tube making the headset more susceptible to coming out of adjustment. This is why a non-Griplock equipped headset will come out of adjustment in rough terrain or over a long ride; the wedge has been essentially hammered out of position. At the same time this hammering effect causes the wedge to clamp down repeatedly on your steerer tube. This repeated clamping could have an adverse affect on steerer tubes in particular those made out of advanced materials like carbon fiber where it could potential score and fatigue the steerer tube. By eliminating the effects of thrust force on a headsets radial preload our patented GripLock™ system is the next generation of headset function and security.

GripLock™ is exclusively equipped on all InSet™ and 1-1/8″ NoThreadSet™ headsets. Upgrades are available for existing non-GripLock equipped 1-1/8” NoThreadSets.
