The Radical Spare ball features caricatures of the two brains behind the Radical brand of bowling balls, Phil Cardinale and Mo Pinel. These two dudes are an odd couple but together produce great bowling balls. This spare ball is an exception to the Radical brand since it does not utilize the advanced technology usually found in a Radical ball. This ball just rolls straight to help pick up those pesky spares. That is still kind of radical!
