Carbon Ti X-Carboring EVO Dura Ace 9200 12-Speed Chainring

X-CarboRing EVO is Carbon-Ti's latest evolution of ultralight road bike chainrings with an aluminium alloy and carbon fibre composite structure

The X-Carboring EVO BCD 110 DA9200 (4 arms) chainrings are made specifically for Shimano Dura Ace and Ultegra 12-speed cranks, as well as the prestigious SRM Origin power meters. The EVO designation identifies these advanced outer chainrings, which adopt the innovations introduced with the X-AXS chainring model specifically for SRAM AXS 12V groupsets.
In particular, the outer chainrings are now machined from thicker carbon fibre sheets to achieve significantly greater stiffness and allow even more elaborate CNC machining. These ramps, together with the redesigned titanium elements that catch the chain and transfer it from the smaller chainring to the larger one, enable lightning-fast shifts with both electronic and mechanical front derailleurs.

Must be fitted together with the X-CarboRing inner chainring (36 x 110 (4 arms) for the 52 x 110 and 34 x 110 (4 arms) for the 50 x 110). For fitting, the dedicated X-Fix ROAD kit is recommended, made from AL7075-T6 alloy, customised with laser engravings and available in a wide range of anodised colours.
