Most fixed sprockets are designed with bevelled teeth, but the Superstar has a curve at the end of every tooth to ensure that the chain feeds smoothly over the sprocket.
Even when paired with a modest chain the transmission stays slick and quiet, and racking up the miles has failed to make the slightest impression on the finish.
Track racers and mile munching fixers will be hard pressed to find a more durable sprocket.
It's available with 14-18 teeth.
