e*thirteen Helix Race Chainring
Best durable chainring for aggressive downhill and freeride mountain biking.
Built for the relentless abuse of bike parks and downhill tracks, this chainring prioritizes rock-solid retention and durability over lightweight minimalism. It’s a heavy-duty upgrade that keeps your drivetrain silent and secure, though the robust construction means you’ll be carrying a bit more mass than a dedicated cross-country setup.
