The Pure Delite damper is a primitive form of low speed compression damping. The working pressure is 20-60 psi. More pressure = more low speed compression damping. Once you get the dual air side set right for your weight and riding style, adjust the Pure chamber pressure to eliminate peddaling bob. But, the higher the pressure, the more small bump compliance you'll lose.
IFP means Internal Floating Piston. This piston seperates the rebound damper oil from the Pure chamber air pressure.
