Supersprox Stealth

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

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

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