BIG PULLEY ASSEMBLY TO IMPROVE TRANSMISSION PERFORMANCE AND DRIVE EFFICIENCY

摘要

The present invention relates to a transmission plate assembly of a rear transmission of a bicycle so as to improve efficiency of drive and transmission performance compared to a conventional pulley. The number of t of a pulley is increased to improve transmission performance, and a POM material having excellent mechanical properties and small mass is used to improve drive efficiency. An increase in the drive efficiency can increase efficiency of cycling motion.;COPYRIGHT KIPO 2018
