Aluminium 7075 T6
Technology CT² : CERAMIC top layer impregnated with TEFLON
Adding CERAMIC ensures a harder surface, longer life, resistance to scratching and the TEFLON® reduces the chain's friction coefficient by over 80% and makes for diminished noise factor, lower over all friction, less need for lubrication and optimized indexation between chainrings.
These chainrings combine the following features : Resistance / light weight / precision / efficiency / easy to use.
