Carbon-Ti X-CarboRing EVO 54×40 Chainring Kit

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 pins.

Every alluminium alloy AL7075 tooth is individually worked to optimize the operation in every condition.
In detail, the outer chainrings are now produced with a thicker carbon fiber plates, 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.

X-Carboring EVO chainrings are available in sizes 54/40, 53/39, 52/36 and 50/34 as well as in the unedited 58/46 and 56/44.Compatibility is ensured for Shimano 11 and 12 speed and SRAM 11 speed groupsets (and chains).

100% made in Italy.
