CYCLOIDⅡmechanism
CYCLOIDⅡis the non-circular chainring developed uniquely by Sugino.
“Autofocus mechanism” assists your pedal stroke to remain smooth and efficient at all time so that your pedaling technique can be dramatically improved. Thus, CYCLOIDⅡis the innovative high performance chainring, totally different from any other ovals
