Supersprox Stealth

A sprocket is practically always made of steel or aluminum. Steel has the advantage of being durable, but it is also a heavy material. As the sprocket is part of the rotating mass, the weight saving is much more noticeable than with a non-rotating mass. A sprocket made only of aluminum would be lighter but too unstable.

Supersprox Stealth combines both materials into a top product for everyday use, the inner part is made of lightweight aluminum and the outer ring is made of steel.
The smaller the sprocket, the higher the gear ratio, which means more max. Speed but less acceleration.

Supersprox is known from various racing series, multiple Dakar Rally winner and supplier to WSBK teams.
