The GripLock headset retention system 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-GripLockTM 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 effect on steerer tubes, in particular those made out of advanced materials like carbon fiber where it could potentially score and fatigue the steerer tube. By eliminating the effects of thrust force on a headset’s radial preload our patented GripLock system is the next generation of headset function and security.
