Direct Mount 42t 1x Chainring - Shimano Compatible

The Easton Direct Mount 42t 1x Chainring delivers the precision and efficiency that modern road, cyclocross, and gravel riders demand. Built from EA90 SL alloy, this chainring strikes the ideal balance between low weight, stiffness, and durability—perfect for riders chasing every watt over mixed terrain.

Its optimized narrow/wide tooth profile locks the chain in place with impressive security, even when the ride gets rough. The updated directional design enhances chain retention and drivetrain smoothness, reducing friction that’s common in 1x setups. Whether hammering through a CX course or grinding gravel miles, this ring delivers crisp, quiet performance mile after mile.

Designed around Easton’s Cinch System spline and a 47mm chainline, it offers seamless integration and clean drivetrain alignment for Shimano 12-speed systems.
