X-Carboring Evo is L’Last evolution of superleggent crowns for racing bikes with composite structure in aluminum alloy and carbon fiber proposed by Carbon-Ti

The X-Carboring Evo BCD 110 Da9200 (4 ARMS) crowns are expressly made for Shimano Ace and Ultegra 12 speeds, as well as for the prestigious Power Meter Origin. The wording Evo distinguishes these external avant-garde crowns that adopt the innovations introduced with the specific X-Axs model for the SRAM AXS 12V groups.
In particular, the external crowns are now obtained from carbon fiber slabs with increased thickness, to obtain a significantly greater rigidity and allow even more elaborate CNC processes. These ramps, together with the redesigned titanium elements, which have the function of “harpooning” the chain by transferring it from the smaller multiplication to the larger one, allow lightning -free derailled with both electronic and mechanical deraillers.

It requires the assembly associated with the internal crown X-Carboring (36 x 110 (4 arms) for the 52 x 110 and 34 x 110 (4 arms) for the 50 x 110). For assembly it is recommended L’Use of the Specific X-Fix Road kit, made of all League al7075-t6 customized with laser engravings and available in a rich range of anodized colors.
