Carbon-Ti X-CarboRing 9100 4-Arm Chainring

Carbon-Ti continues to impress with their high caliber engineering and design.  The incredibly advanced X-CarboRing is now available in a newer 4-arm, 110 BCD configurations.  This new chainring will work with Dura-Ace FC-9100 / 9000 series, Ultegra FC-8000 series, and SRM Origin 9100 / 9000. These chainrings are available in 53, 52, 50 tooth counts. 

Weight is kept low using a mixture of carbon (inner body), AL7075-T6 aluminum (teeth), and titanium (shift pins). Using these varied materials, Carbon-Ti is able to achieve both a lightweight and highly functional ring, the aluminum and titanium parts aiding in shift quality and durability.  The carbon fiber inner ring is bonded to a 7075 T6 aluminum tooth pattern, resulting in a unique way to drop grams on your next build, while simultaneously adding a touch of high-end class. By reducing weight from your drivetrain, the amount of energy required for a revolution of the crank is decreased, therefore optimizing pedal stroke and increasing power. Additionally equipped with special carbon fiber shift ramps, the Carbon-Ti X-Ring is designed to shift well under pressure, while remaining as lightweight as possible.

These are compatible with Shimano Dura Ace 9100, Ultegra 8000 or SRM Origin 9100 cranksets
