CY5-SWN

Ultra-high performance, Wide and Narrow tooth profile, Front Single Chainring, with superior functionality to any other ovals, for Sugino OX Series, Mighty Series and standard PCD110 cranks (5 Bolts).

More and more bikes that are intended for long ride, hill climb, gravel and cyclocross are built with wide-range cassette drivetrains. Thus, there's an undeniable appealing simplicity to a single-ring setup in various situations.

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.

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

"What is Autofocus mechanism?"
When the forth 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
