The Headshok operate s through the use of a telescoping steerer tube that travels inside the headtube of the frame itself. Unlike a suspension fork, the fork legs in a Headshok system are completely rigid. This is a simple solution to the problem of independent fork leg compression. With a Headshok, the fork legs and the front wheel always travel in unison, giving it unparalleled tracking performance. The steerer tube of the Headshok and the headtube of the frame share over four inches of space.
Shims take up every millimeter of the gap between the two tubes.
Unlike the nylon bushings in a suspension fork, these shims won't deteriorate over time, so your tracking precision will never be compromised. Beyond this, the steerer glides on four towers of 22 roller bearings, giving it stiction-free responsiveness to small bumps and repetitive washboard bumps. No suspension fork can match the Headshok's sensitivity to slight hits. The Headshok is sealed up by a shock boot that won't slip and by a pair of massive cartridge bearings that simply won't admit contamination. This means more hours of riding without having to perform maintenance.
