10V STRONGLIGHT CT² Shimano Dura-Ace 7900 130 mm outdoor chainring

The outer deck STRONGLIGHT CT2 Shimano Dura-Ace 7900 is a high-performance road chainring that's both robust and precise, thanks to its design combining high-precision machined 7075 T6 aluminum and CT² technology, consisting of a ceramic coating impregnated with a layer of Teflon.

The ceramic coating enhances hardness, longevity and abrasion resistance, while the Teflon coating reduces the chain's coefficient of friction by more than 80%, thus reducing noise, friction and lubrication, and optimizing chainring indexing.

Combining strength, lightness, precision, efficiency and comfort of use, this CT2 chainring is designed for use with the Shimano Dura-Ace 7900 10-speed crankset with 130 mm center distance (BCD).
