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 (4 arms) are made for SRM Origin power meters and Rotor INSpider cranks. 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 plate, 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.
Compatibility is ensured for Shimano 11 and 12 speed and SRAM 11 speed groupsets (and chains).
100% made in Italy.
