STRONGLIGHT CT2 Corona dentata 39T 11 velocità interno 110BCD per Dura-Ace 9000/Ultegra 6800/105 5800

The STRONGLIGHT CT2 Shimano Dura-Ace 9000 / Ultegra 6800 / 105 inner chainring is a high-performance road chainring that is both robust and precise thanks to its design, which combines high-precision machined 7075 T6 aluminium and CT² technology consisting of a ceramic coating impregnation of a Teflon layer.

The contribution of ceramic allows for better hardness, longer life and anti-abrasion, while Teflon reduces the coefficient of friction of the chain by more than 80%, providing a reduction in noise, friction and lubrication and optimising indexing between the plates .

This CT2 chainring combines strength, lightness, precision, efficiency and ease of use and is designed here for Shimano Dura-Ace 9000 / Ultegra 6800 / 105 11-speed cranksets with 110 mm centre distance (BCD).
