Carbon-Ti X-CarboRing Inner 110 BCD 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, 40, 39, 36, and 34 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. The inner rings works with all 4-bolt 110 BCD cranks.

For the accompanying Outer(Large) chainring, please go here to order either the 9200, 9100 or standard 4-bolt 110 BCD chainring.

Not compatible with SRAM AXS 12-speed groups (choose the specific 110 BCD X-AXS chainring or 107 BCD X-AXS chainring).
