Wide-Narrow Chainring

Alternating narrow and wide teeth makes the chain more secure on the ring and eliminates chain drop, optimized design for front-single chainring.


CYCLOID?is 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, CYCLOID?is the innovative high performance chainring, totally different from any other ovals "

What is Autofocus mechanism?" When the force is applied to the pedal, the chain moves outward. You feel the ring increases the diameter as the chain runs higher on the ring. As amount of moving will fluctuate by the force applied, it maximizes the benefits of non-circular ring, and assists your pedal stroke to remain efficient. *there is no need of pedal stroke analysis to identify peak point or adjustment of mounting position.

  • Super low Q-Factor 145mm", perfectly symmetric ensures smoother and efficient pedaling.
  • "Large ankle clearance" keeps the shoe from rubbing the crank.
