Secure chain retention with the FSA Megatooth Chainring and its 1x-optimized tooth profile
We trust our drivetrain most when it’s built around components that don’t let go—literally. That’s why we run the FSA Megatooth 1x Chainring on our trail and all-mountain builds. Whether we’re pedaling through techy climbs or rallying over root webs, this chainring keeps our chain locked down and our ride smooth.
Made from lightweight CNC-machined 7075-T6 aluminum, this ring is engineered for stiff, efficient power transfer and long-term durability. The alternating thick and thin teeth improve chain engagement, while the extended Megatooth profile enhances retention on rough terrain. Designed for use with 10- and 11-speed 1x drivetrains, it bolts directly to standard 104mm BCD cranks, making it a fast upgrade that punches way above its weight.
