Offers viscous damping to make bicycles safer by inhibiting the uncontrolled steering oscillation known as speed wobble Microthin plates are inter-leaved in an encapsulated cartridge, as they rotate against each other, a fluorocarbon gel between each layer provides viscous damping and stops the oscillation of the handlebars before it grows to a dangerous level Ideal for the daily use and abuse seen by modern ebikes, loaded bikepacking/gravel bikes and even aiding in safety for kids bikes
