STRONGLIGHT CT2 Plato 36D (46D) 11-vel Interior 110BCD para Dura-Ace R9100

The Shimano Dura-Ace 9100 STRONGLIGHT CT2 inner chainring is a robust and efficient top-of-the-range chainring that combines high-precision machined 7075 T6 aluminium and CT² technology, consisting of a ceramic coating with impregnation of a PTFE layer .

The contribution of ceramic allows for better hardness, longer life and an abrasion resistant effect, while PTFE reduces the coefficient of friction of the chain by more than 80 %, providing a reduction in noise and friction.
