Only the highest quality additives are used in the r.s.p. CHAIN WAXes:
Such as tungsten sulphide (WS2). Tungsten sulphide has an incredibly low coefficient of friction of 0.03 – better than Molybdenum, PTFE or even wet ice on wet ice! Increases power transmission and reduces wear. Very low friction – works over a wide temperature range from -270 °C to +650 °C
