FSA Megatooth E-Bike Sprocket

This sprocket is designed for 104mm 4-bolt mounting patterns. It is compatible with 9, 10, and 11-speed chains, as well as SRAM 12-speed Eagle systems.

E-bikes exert significantly higher torque on the drivetrain than standard bikes. Steel is used here to provide the durability and wear resistance needed to handle that extra power without premature tooth wear.

The combination of a narrow-wide tooth design and a longer tooth profile creates a deeper, more secure engagement with the chain. This effectively locks the chain in place, which drastically reduces the chance of it dropping when you are riding over rough, technical terrain.

While you technically could mount it to any 104mm 4-bolt crankset, it is heavier than standard aluminum chainrings. It is specifically engineered for the high-torque demands of e-bikes, so it may be overkill for a traditional mountain bike setup.

This specific model is a 36-tooth chainring. Be sure to check your current setup to ensure a 36T ring provides the gear ratio you need for your local trails.
