Carbon-Ti X-CarboRing EVO BCD110x4 碳纖維齒片 (DA 9200/ ULT 8100 系列適用)

X-CarboRing EVO is the latest evolution ofsuper-light chainrings for racing bikes with a composite structure in aluminumalloy and carbon fiber proposed by Carbon-Ti.

X-Carboring EVO BCD 110 DA9200 (4 arms) aremade for Shimano Dura Ace and Ultegra 12 speed cranks, as well as for thetop-rated SRM Origin power meters. The wording "EVO" distinguishesthis new generation of external chainrings which adopts the well knowninnovations that already belong to the latest "X-AXS" chainringsspecific for SRAM AXS 12s groupsets.

In detail, the outer chainrings are nowproduced with a thicker carbon fiber plates, to obtain a higher stiffness andto allow a more elaborate CNC machining. These ramps together with theredesigned titanium elements have the function of "harpooning" thechain, transferring it from the smallest to the largest chainring and allowfast and precise up-shiftings and down-shiftings with both electronic andmechanical derailleurs.

X-Carboring EVO chainrings are available insizes 54/40, 53/39, 52/36 and 50/34 as well as in the unedited 58/46 and56/44.Compatibility is ensured for Shimano 11 and 12 speed and SRAM 11 speedgroupsets (and chains).

Not compatible with SRAM AXS 12 speedgroups (choose the specific X-AXS chainrings).

It is recommended to use the X-CoverDA9200. It is a specific kit for Shimano DuraAce 9200 12s cranks and is made upof AL7075-T6 alloy.

Alternatively, the X-Fix ROAD kit isavailable with customized laser engravings and in a wide range of anodizedcolors.
