Enhance your 1x drivetrain with the FSA Gossamer Pro MegaTooth Chainring, a 44T narrow-wide chainring optimized for reliable shifting and chain retention on 11-speed road and gravel bikes. Featuring the patented MegaTooth profile with alternating thick-thin teeth, it prevents chain drops while improving mud clearance and engagement, making it ideal for mixed-terrain riding and high-mileage endurance. CNC-machined from premium AL7075 alloy with an anodized black finish, it offers superior strength and lightweight performance (~80g). The 120mm BCD 4-bolt design ensures compatibility with Gossamer Pro AGX and Omega cranksets, delivering seamless integration for Shimano 10/11-speed, SRAM 10/11-speed, and FSA 11-speed systems. A must-have for riders seeking drop-free precision without a chain guide.
