*GIGAS is super hard and light alloy material. It is called GIGAS because the tensile strength is greater than 1 Giga Pascal. The specific strength is more than twice as high as that of heat-treated chromoly steel.

S-cubic coating (S3) is smooth and shiny combines high hardness with low friction coeffcient can minimize the chain driving resistance and achieve more effective power transmission, will offer amazing performances at track races wherein the winner is often decided by hundredths of a second. The friction resistance is less than half that of the titanium coating.

*Use only“neutral” cleaning agents for Super Series (S3 finish). Liquids and others which contain acid or alkali will harm finished surface and can cause malfunction to the product.
