Tray made of 7075 T6, benefiting from the technology: CT².
(Ceramic coating with a Teflon layer impregnation)
The contribution of the ceramic provides better hardness, durability, and an anti-wear effect, while Teflon reduces the friction coefficient of the chain by more than 80%, leading to a decrease in noise, friction, and lubrication, and optimizes indexing between the chainrings.
