The world-famous chainring used by Olympic and World Championship medalists.

Stiffer and more mighty than any other track chainring, the Super Zen is the most reliable, smoothest, straightest chainring and features S-Cubic (S3) coating.

S-Cubic coating is smooth, very shiny and combines high hardness with low friction to minimize chain resistance and achieve more effective power transmission.

Sugino advises only using mild neutral cleaning agents for Sugino Super Series w/ S3 coating. Liquids and other cleaners which contain acid or alkali will harm the finished surface.
