Availability: Out of stock

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 9100Ultegra 8000 or SRM Origin 9100 cranksets

IF YOU ARE LOOKING FOR THE INNER CHAINRING, PLEASE GO HERE TO ORDER THE 34T, 36T OR 39T. The inner ring doesn't change from the original 4-arm version.
