This Pro-tek 525 Pitch (5/16" chain roller width) 14 tooth front sprocket is completely CNC machined to exact tolerances from 4140 nickel-chromoly steel resulting in accurate tooth profiles. This sprocket is available in five tooth sizes - 13T, 14T 15T, 16T, 17T. This sprocket is Not gear-hobbed like other sprockets insuring that the teeth fit precisely on the chain rollers which insures maximum chain and sprocket life along with a more efficient power transmission. The sprocket is then lightened with drilled holes to save on rotating mass. Every lb of rotating mass equates to a 4 lb weight reduction. The sprocket is then case hardened to Rc 58-60 and finished with a silver zinc plating for added durability and protection from corrosion. This sprocket is brand new in original packaging manufactured in the US from Pro-tek, a leading manufacturer in the industry now for over 25 years.

This determines how engine RPM translates into wheel speed by bike. Changing sprocket sizes, front or rear, changes this ratio which changes the way bike puts power to the ground. With respect to stock gearing, installing a smaller front sprocket (fewer teeth), or a larger rear sprocket (more teeth), provides a lower gear ratio increasing acceleration of the bike but decreasing top speed. Conversely, installing a larger front or smaller rear provides a higher ratio which decreases the acceleration but increases top speed. Every one tooth change in the front is equal to a 3 tooth change in the rear. So a rear change more than two teeth means adding/removing chain links.
