Inner Chainring 12 Speed STRONGLIGHT CT² for DURA-ACE FC-R9200 110mm

The Inner Chainring STRONGLIGHT CT2 DURA-ACE FC-R9200 Chainring 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 with a Teflon impregnation.

The addition of ceramic increases the chainring's hardness and longevity, while improving its resistance to abrasion. Teflon reduces the chain's coefficient of friction by over 80%, ensuring less noise, friction and lubrication, and optimizing indexing between chainrings.

Combining strength, lightness, precision, efficiency and comfort of use, this CT2 inner chainring is designed for DURA-ACE FC-R9200 12-speed cranksets with 110 mm center distance (BCD).
