FSA Pro MegaTooth Chainring

This chainring is designed for 11-speed systems and uses a specific 3-bolt mounting interface with an 86mm BCD. Before purchasing, verify that your crankset is compatible with the 3-bolt mounting standard, as it will not fit traditional 4-bolt or direct-mount systems.

The narrow-wide tooth profile alternates between thin and thick teeth to match the inner and outer links of your chain. This creates a tight, secure fit that significantly reduces the risk of your chain dropping, even when you are riding over rough, technical terrain.

A 28T chainring is on the smaller side, which makes it an excellent choice if you prioritize climbing efficiency and need easier gearing for steep ascents. If you frequently ride flat trails or prefer higher top speeds, you might find yourself spinning out and may want to consider a larger tooth count.

Because of the specialized MegaTooth profile, this chainring is designed to hold the chain securely on its own. Most riders find that a chain guide is unnecessary for trail riding, though some aggressive downhill riders may still choose to run a lightweight guide for extra peace of mind.
