Emulsion Shock --

When a shock compresses, the portion of the shaft entering the body displaces the shock oil. The oil needs a room to expand to compensate for this, or the shock will essentially 'lock up'. With emulsion style shocks (shocks without bladders or reservoirs), tiny air bubbles are left in the shock oil when the shock is built. These bubbles compress as the shock compresses, giving the oil room to expand. Over time, the air bubbles rise to the top of the shock, forming a pocket of air - so for best performance, emulsion shocks need to be 'pumped' a few times before running to re-emulsify the oil.
