New 3-in-1 surprise caps enable construction in 3 various designs – emulsion / rebound / zero rebound, to complement shock dampening traits to different driving designs and differing track conditions. The Emulsion configuration uses an O-ring to seal limitation to human anatomy, mixing oil and atmosphere within the shock. Typically provides exemplary traction on numerous surfaces and is recommended as a starting point for some typical track conditions. The Rebound alternative utilizing the mobile membrane layer is much better matched to reduce traction and flat slippery tracks. This surprise set-up gets the numerous rebound right out from the three create choices. The Zero Rebound setup created by utilising the ribbed membrane layer layer is way better suited to super bumpy tracks. This set-up doesn't always have rebound.
