X-CarboRing EVO is the latest evolution of super light crowns 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 expressly made for Shimano Dura Ace and Ultegra 12 speed cranks, as well as for the prestigious SRM Origin power meters. The wording EVO distinguishes these avant-garde external chainrings that adopt the innovations introduced with the X-AXS chainring model specific for the SRAM AXS 12s groupsets.

In particular, the outer crowns are now made from carbon fiber plates with increased thickness, to obtain considerably greater rigidity and allow even more elaborate CNC machining. These ramps, together with the redesigned titanium elements, which have the function of "harpooning" the chain by transferring it from the smallest to the largest chainring, allow lightning-fast derailments with both electronic and mechanical derailleurs.
X-Carboring EVO are available in sizes 53/39, 52/36 and 50/34, as well as in the brand new 54/40. Compatibility is ensured for Shimano 11 and 12 speed, Campagnolo 11 and 12 speed and SRAM 11 speed groupsets (and chains).
