Aero Gravel 8-Bolt Chainring

The 5Dev Aero Gravel 8-Bolt Chainring was built for riders chasing every watt of efficiency on the road or gravel. Precision-machined in San Diego from high-strength 7075 aluminum, this chainring blends sleek aerodynamics with proven durability for serious 1x performance. Whether tackling a long gravel grind or a fast group ride, every detail is optimized for smooth power transfer and quiet, confident shifting.

Designed around SRAM’s 8-bolt direct mount interface, the Aero Gravel Chainring delivers a clean setup that’s compatible with both Flat Top and Eagle SRAM chains, as well as Shimano 12-speed drivetrains. The exclusive Shark Fin tooth shaping cuts down on chain noise and improves retention—especially handy for “mullet” builds pairing road cranks with MTB cassettes.
