                  a underdriven crank pulley is a light weight pulley for the crank, which also gets rid of your harmonic pulley i believe. there are light weight pulleys for the accessories alone. also ive read you shouldnt use a underdriven crank pulley in correlation with a light flywheel. correct me if im wrong. also not trying to thread shit at all. i'd love to have a lightweight crank pulley.
