ViscoSet offers viscous damping to make bicycles safer by inhibiting the uncontrolled steering oscillation known as speed wobble. Speed wobbles 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.
