What is the Difference Between High and Low Speed Compression Adjustment: 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 area of adjustment. Low speed is used for controlling chassis movements, 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 speed is especially important, where every bit of grip available is critical.
