DRIVE SPROCKET 520 17T

Manufactured from case-hardened chromoly steel for unparalleled strength and durability

Parkerizing surface treatment prohibits rust and corrosion, building resistance against those agents, resulting in a longer lasting, better appearance

Most race applications feature drilled weight-reduction holes (depends on application/tooth size)

Constructed of the same great quality and specifications that the Japanese OEMs have trusted and used since 1946
