FSA Megatooth Chainring

No, the FSA Megatooth is specifically engineered for 10 and 11-speed systems. Using it with a 12-speed chain may cause fitment issues or premature wear due to the specific tooth profile.

The narrow-wide design alternates the width of each tooth to match the inner and outer links of your chain. This creates a tight, secure interface that significantly reduces the chance of the chain dropping, even on rough or bumpy terrain.

This chainring uses a 110 mm BCD (Bolt Circle Diameter) and a standard bolt-on mounting system. Before purchasing, verify that your crankset matches this 110 mm measurement to ensure a proper fit.

7075/T6 aluminum is a high-strength alloy commonly used in aerospace applications. In this context, it provides the necessary stiffness for efficient power transfer while remaining lightweight and durable enough to withstand the rigors of off-road riding.

Because of the specialized long tooth profile and narrow-wide design, most riders find that a chain guide is unnecessary for 1x setups. The chainring is designed to retain the chain securely on its own, even without additional guides.
