STRONGLIGHT CT2 Plateau 53 dents (39 dents) 11 vitesses externe 110BCD pour Dura-Ace R9100

The STRONGLIGHT CT2 Shimano Dura-Ace 9100 outer chainring is a robust and high-performance high-end chainring that combines high-precision machined 7075 T6 aluminium and CT² technology, consisting of a ceramic coating with impregnation of a Teflon layer.

The addition of ceramic provides better hardness, longer life and an anti-abrasion effect, while Teflon reduces the chain's coefficient of friction by more than 80%, reducing noise, friction and lubrication and optimising indexing between plates .

This CT2 chainring combines strength, lightness, precision, efficiency and ease of use and is designed here for the Shimano Dura-Ace 9100 11-speed crankset with 110 mm centre distance (BCD).
