Inner Chainring 12sp STRONGLIGHT CT² for ULTEGRA/105 FC-R8100/R7100 110mm

The STRONGLIGHT CT2 Shimano Ultegra/105 R8100/R7100 inner chainring is a high-performance road chainring that is both robust and precise, thanks to its design combining high-precision machined 7075-T6 aluminium and CT² technology, consisting of a ceramic coating with a teflon layer impregnation.

The ceramic addition increases the hardness and longevity of the chainring, while improving its abrasion resistance. The teflon reduces the chain friction coefficient by more than 80%, thus ensuring a reduction in noise, friction and lubrication requirements, and optimises indexing between chainrings.

Combining strength, lightness, precision, efficiency and ease of use, this CT2 inner chainring is designed for 12-speed Shimano Ultegra 8100 and 105 R7100 cranksets with a 110 mm bolt circle diameter (BCD).
