Stealth (Tri-Metal) sprockets were born from a desire to create the highest quality and most technologically advanced sprockets in the world. The Stealth (Tri-Metal) is a combination of long lasting steel and lightweight aluminium that utilises the best of both materials. The idea was first developed to satisfy the requirement of drag racers, who traditionally use steel construction sprockets because aluminium sprocket teeth can not survive the high torque delivered through the chain drive system. But steel sprockets are very heavy. Supersprox engineers conceived and developed the combination of the two materials in 2000–2001. The sprockets were first used on the bikes of our World Championship sponsored riders with the likes of Husqvarna World Enduro team. These teams and riders know how this type of technology can offer them prolonged system performance and reduced power loss. Supersprox have counted 4 world titles since that time.
