Pro-tek front sprockets are completely CNC machined to exact tolerances from 4140 nickel-chromoly steel resulting in a quality product.  None of the Pro-tek front sprockets are gear hobbed, but are lightened with drilled holes to save on rotating mass.  Every lb of rotating mass equates to a 4 lb weight reduction. The sprockets are then case hardened to Rc 58-60 and finished with a zinc plating for added durability and protection from corrosion.  Made in the USA, normally retail for $29.95.  This is for a 520 Pitch front sprocket 14 tooth.
