Vintage Cannondale – Head Shok Information HEADSHOK–HISTORY & FEATURES The Headshok suspension fork was first introduced in 1992. It features 4 strips of needle bearings.

Each strip contains 22 bearings for a total of 88. Each of the needle bearing strips are “sandwiched” between an inner race of variable thickness and an outer race. Together, with an aluminum outer tube and a steel or aluminum inner steerer tube, they form a telescoping assembly. With this design Cannondale has a system that rolls and does not slide like other suspension forks. This also keeps stiction to a minimum. This assembly is pressed into the crown of a set of rigid aluminum fork blades.

We use this “rigid” design to have a flex-free system that you can “point-and-go”. The Headshok fork will not twist and bend around while under load like most conventional forks. Unlike most forks, the Headshok cartridges can be upgraded, sometimes resulting in more travel.

The following is a list of what was released for that year, some forks were carried into the next year.
