Lightness or longevity... The rear sprockets are fundamental elements in the composition of a chain kit. SuperSprox mixes materials to offer performance worthy of aluminum with a lifespan equivalent to that offered by steel. Here are the Stealths.
It is essential to properly maintain your chain kit if you want it to last over time, however the choice of materials also has its role to play in this equation: a reinforced chain kit for a longer lifespan at the expense of weight, playing directly on the feeling and particularly in terms of power or a lighter version offering more lively boosts without being violent.
To win on both counts, the Stealth crowns (which can be equipped with a gearbox output sprocket and a DID chain) rely on a lightweight CNC-machined hub in anodized Duralloy and an outer steel track, riveted together.
Being able to weigh up to 50% less than a steel version, our experiences show a reduction of around 50 to 100 grams compared to a full steel element. It may not seem like much, but the blind feeling is there...
What the manufacturer says:
SuperSprox Stealth bimetal crown. The lightness of aluminum and the strength of steel.
Up to 50% lighter than a steel sprocket and three times stronger than an aluminum sprocket, the Stealth is designed for extreme driving conditions and to absorb powerful engine torques.
