X-CarboRing is the next-generation of superlight aluminium/carbon fiber road chainrings by Carbon-Ti. The main body of structural carbon fiber presents CNC workings and titanium shaped pins for amazing shifting perfomance with mechanical or electronic derailleurs. Every alluminium alloy Al7075 tooth is individually worked to optimize the operation in every condition. The X-CarboRing carbon fiber chainring range is enhanced by two new models (called X-AXS) specific for SRAM Red and Force eTap AXS 12s groups for cranksets 5 and 4 arms. These chainrings permit to ride with THM Clavicula (or other BCD 110 5 arms compact cranksets) or SRM Origin BCD 110 4 arms cranksets with the new SRAM 12s electronic groups. The same gear sizes, prescribed by SRAM, are available and thought (50/37, 48/35, 46/33) to obtain the maximum performance.
