SUPER GIGAS Sprocket, high
polish finish, ultra light, perfectly round, low friction and very smooth,
made of GIGAS aluminum alloy, comes in three finishes.
*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.
SUPER GIGAS Platinum-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.
