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 chain rings.
These chain rings combine the following features resistance / light weight / precision / efficiency / easy to use.
Outer chainring available in: 48/50/51/52/53 teeth 76 grs
Inner chainring available in: 34/36/38/39/40/42 teeth 35grs
Available in the following diameters:
- 130 mm (Shimano®)
- 135 mm (Campagnolo® )
