Hunting Tooth • A unique construction that allows for extended service life. • Hunting tooth sprockets have an odd number of teeth and are half the pitch of the mating chain. Every time the sprocket makes a revolution, the chain engages with one set of teeth, ahead of the previously engaged set. Hence, each sprocket tooth only sees engagement every other rotation. Double Duty • An innovative construction that allow for extended service life. • Double Duty sprockets are double cut and have an even number of teeth. Utilizing strategic, manual indexing, this design can provide extended service life, somewhat similar to a hunting design for an even tooth setup.
