Carbon-Ti X-CarboRing EVO 54/40 x 110 DA9200 (4-Arm) Chainrings

The Carbon-Ti X-CarboRing EVO 54/40 is a premium chainring set engineered for high-performance road cycling and elite-level builds. Designed specifically for Shimano’s 12-speed platforms, this 54/40T configuration delivers a race-focused gearing combination ideal for powerful riders and fast terrain.

Manufactured in Italy, the EVO series combines a structural carbon fibre core with CNC-machined AL7075-T6 alloy teeth and Grade 5 titanium hardware. This advanced composite construction ensures exceptional stiffness, reduced weight, and precise front shifting under load, even in demanding race conditions.

Optimised shift ramps and titanium pins enhance chain engagement, delivering fast and reliable transitions between rings for both electronic and mechanical drivetrains.

Designed around Shimano’s 110 BCD 4-arm interface, this DA9200-specific configuration integrates seamlessly with modern Dura-Ace and Ultegra cranksets, making it an ideal upgrade for performance road bikes and power meter-equipped builds.
