Extra light !
These chainrings, made from 7075 T6, feature: CT² technology ( 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.

We have also optimized CSA indexation in order to make it possible for even the most demanding of cyclists to INTENSIVELY shift between chainrings, even under full strain (in competition and extreme circumstances) !

The anti "chain suck" CSA indexation allows for fast and supple shifting, even under extreme conditions (mud, rocks...)
