FSA Afterburner Chainring

No, this chainring is specifically designed for the FSA Afterburner Modular crank system. It uses a proprietary direct-mount interface that will not fit standard cranksets from other brands.

This chainring is optimized specifically for Shimano 12-speed drivetrains. While it may physically mount to the crank, the tooth profile is engineered for the tighter tolerances of 12-speed chains, so we do not recommend using it with 11-speed setups.

The Megatooth design uses a thick-thin tooth pattern that locks the chain securely onto the ring. This significantly reduces the risk of chain drops during aggressive riding and rough terrain, eliminating the need for a separate chain guide in many setups.

The ring is CNC-machined from AL7075/T6 aluminum, which is a high-strength alloy commonly used in aerospace applications. It offers an excellent balance between low weight and the structural rigidity required to handle the high torque of mountain biking.

Yes, because it is a direct-mount component, you will need the appropriate FSA lockring tool to remove and install the chainring onto your Afterburner crank arm. Ensure you have the correct tool for your specific crank interface before starting.
