MTB Chainrings

Chainrings live a hard life. Ours wouldn't have it any other way. Mountain bike chainrings engineered for chain retention, durability, and cross-compatibility. The M4 narrow-wide tooth profile keeps your chain locked in place while reducing noise and extending wear life. Works with Shimano®, SRAM®, and TRP® 11 and 12-speed drivetrains, including T-Type™. Direct mount, 8-bolt, and 3-bolt options from gravity-rated aluminum to long-wearing steel.

More about e*thirteen MTB Chainrings

Every pedal stroke, every rock strike, every mud-caked mile. Our chainrings were built for this.

Helix Race is CNC machined from 7075-T6 aluminum at just 56g (32T). Available in direct mount for e*thirteen cranks, 8-bolt for the new Helix Race Carbon, and 3-bolt for SRAM® cranks. Flip-flop design accommodates Boost and Super Boost chainlines with a single ring.

Helix Race GR exceeds ASTM 5 standards for downhill, bike park, and freeride. Built for the riders who regularly test the limits of their equipment.

Helix Steel delivers maximum durability at a price point that makes sense for hardtails, winter bikes, and builds where longevity beats weight savings.

SL Guidering and UL Chainring offer the lightest options for XC racing and weight-conscious trail builds.

Every ring is cross-compatible with Shimano®, SRAM®, and TRP® drivetrains. No ecosystem lock-in.
