X-CarboRing EVO 55 x 110 DA9200 (4 arms)

X-CarboRing EVO is the latest evolution of super-light chainrings for racing bikes with a composite structure in aluminum alloy and carbon fiber proposed by Carbon-Ti.

X-Carboring EVO BCD 110 DA9200 (4 arms) are made for Shimano Dura Ace and Ultegra 12 speed cranks, as well as for the top-rated SRM Origin power meters. The wording "EVO" distinguishes this new generation of external chainrings which adopts the well known innovations that already belong to the latest "X-AXS" chainrings specific for SRAM AXS 12s groupsets.

In detail, the outer chainrings are now produced with a thicker carbon fiber plates, to obtain a higher stiffness and to allow a more elaborate CNC machining. These ramps together with the redesigned titanium elements have the function of "harpooning" the chain, transferring it from the smallest to the largest chainring and allow fast and precise up-shiftings and down-shiftings with both electronic and mechanical derailleurs.

X-Carboring EVO chainrings are available in sizes 58/46, 56/44, 54/40, 53/39, 52/36 and 50/34, as well as in the unedited 60/46, 55/40, 55/38, 54/38. Compatibility is ensured for Shimano 11 and 12 speed and SRAM 11 speed groupsets (and chains).

It is recommended to use the X-Cover DA9200. It is a specific kit for Shimano DuraAce 9200 12s cranks and is made up of AL7075-T6 alloy.

Alternatively, the X-Fix ROAD kit is available with customized laser engravings and in a wide range of anodized colors.
