Carbon-Ti X-CarboRing EVO BCD110x4 碳纖維齒片 (DA 9100/ ULT 8000 系列適用)

The round X-CarboRing EVO has the highest level of development of Carbon-Ti chainrings. A sprocket made of a 7075-T6 aluminum alloy is placed on a base made of 3K carbon fiber. The shift ramps are made of high-quality grade 5 titanium, which guarantee buttery-smooth gear jumps. Specially designed for racing, this mix of materials is the best compromise between durability and weight.
The back of the carbon-ti chain ring is artfully milled to save even the last gram and enable perfect shifting. The use of aluminum as the tooth material ensures a long service life.

Hints:
For optimal shifting performance, CARBON-TI recommends the combination with the inner CARBON-TI X-CarboRing chainrings in the gradations 54/40, 53/39, 52/36 or 50/34. Using other compilations is not recommended.
The chain ring is not suitable for SRAM AXS.
