This is a replacement headset top part only.
ViscoSet (patent-pending) offers viscous damping to make bicycles safer by inhibiting the uncontrolled steering oscillation known as speed wobble. "Speed wobble" or "head shake" are vibrations that start small and get worse due to harmonics. This frightening shimmy can affect the handling of any bicycle under certain conditions and is the result of many different factors.

Utilising specially designed damping plates above the bearing in the upper assembly, ViscoSet stops the oscillation before it can grow to a dangerous level. These micro-thin plates are inter-leaved and connected to both the frame and the fork's steerer tube. As they rotate against each other, a fluorocarbon gel between each layer provides maintenance free viscous damping, preventing the dreaded speed wobble and allowing riders to maintain control.

ViscoSet's damping plates have the ability to be repositioned within the headset, creating several "tune" configurations. The 12 damping plates housed within ViscoSet come standard interlaced with fluorocarbon gel within the headset cup, forming 11 friction surfaces that create damping in steering. If the damping force is too large for the desired ride experience, the damping plates can be reconfigured within the headset cup to achieve the appropriate amount of steering damping.
