High and low speed damping is determined by the speed at which the shock is moving. For example, high-speed bumps can be compared to hitting a curb or a large bump in the road surface. Typically, this is a rider-comfort adjustment area. Low speed is used to control chassis movement, grip, and tire wear. When the bike is in the corner and the chassis is loaded, any slight variation in the track surface would be considered low speed. If a shock can’t absorb the variation, the grip would be reduced. In a race environment, the ability to adjust both high and low speeds is especially important, where every bit of grip available is critical.
