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 are made for all compact cranksets such as the THM Clavicula SE or the Quarq Dzero AXS powermeter. The EVO wording distinguishes these cutting-edge external chainrings which adopt the innovations introduced with the X-AXS chainring model specific for SRAM AXS 12s groupsets.
In particular, the external crowns are now made from carbon fiber sheets with increased thickness, to obtain significantly 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 gear to the largest one, 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 new 54/40. Compatibility is ensured for Shimano 11 and 12 speed, Campagnolo 11 and 12 speed and SRAM 11 speed groupsets (and chains).
The compatible fixing screw kit is the X-Fix ROAD: made of AL7075-T6 alloy, customized with laser engravings and available in a rich range of anodized colours.
Like all Carbon-ti products, the new X-Carboring EVOs are also 100% made in Italy.
Crown in AL7075-T6 aluminum alloy, structural carbon fiber with 3K glossy finish and Grade 5 Titanium pin.
50-tooth external gearing and 110 mm bolt circle (BCD), 5 arms, compatible with compact cranks such as THM Clavicula SE or Quarq Dzero.
Compatible with Shimano Dura-Ace 9200, Ultegra 8100, Campagnolo 12-speed groupsets and all previous 11-speed groupsets.
Not compatible with SRAM AXS 12-speed groupsets (choose specific X-AXS chainrings).
For assembly, we recommend using the specific X-Fix ROAD kit, made of AL7075-T6 alloy customized with laser engravings and available in a wide range of anodized colours.
