Light, firm and aerodynamic! These time trial chainrings, made of CNC machined 7075-T6 aluminum, feature StronglightŽs CT² technology (Ceramic top layer impregnated with Teflon). Adding Ceramic ensures a harder surface, longer life and resistance to scratching. The Teflon reduces the chain's friction and makes for diminished noise factor, lower over all friction, less need for lubrication and optimized CSA-indexation between chainrings. Available with various teeth counts.
