Carbon-Ti X-CarboRing EVO 4-Bolt Carbon Chainring

Carbon-Ti continues to impress with their high caliber engineering and design.  The incredibly advanced X-CarboRing, originally available in a 5-bolt 110BCD & 130BCD, is now available in 4-arm 110 BCD configurations.  This is great news for owners of cranksets such as the Dura-Ace FC-9200 / 9100 / 9000 series, Ultegra FC-8100 / 8000 series, SRM Origin 4-arm series and Rotor Power Meter INSpider cranks. They are available in 54, 53, 52, 50 tooth counts.

Weight is kept low using a mixture of carbon (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.

These chainrings are compatible with Shimano 11 & 12-speed, SRAM 11-speed, and Campagnolo 11 & 12-speed drivetrains.
