X-CarboRing EVO is the latest evolution of superlight chainrings for road bikes with a composite structure made of aluminum alloy and carbon fiber offered by Carbon-Ti

The X-Carboring EVO BCD 110 DA9200 (4 arms) chainrings are specifically made for Shimano Dura Ace and Ultegra 12-speed cranksets, as well as for the prestigious SRM Origin power meters. The EVO designation distinguishes these cutting-edge outer chainrings that adopt the innovations introduced with the X-AXS chainring model designed for SRAM AXS 12V groups.
In particular, the outer chainrings are now made from carbon fiber plates with increased thickness to achieve significantly greater stiffness and allow even more elaborate CNC machining. These ramps, together with redesigned titanium elements that function to "hook" the chain transferring it from the smaller to the larger chainring, enable lightning-fast shifts with both electronic and mechanical derailleurs.

Requires installation paired with the inner X-CarboRing chainring (36 x 110 (4 arms) for the 52 x 110 and 34 x 110 (4 arms) for the 50 x 110). For installation, it is recommended to use the specific X-Fix ROAD kit, made from AL7075-T6 alloy customized with laser engravings and available in a wide range of anodized colors.
