ethirteen Helix Race Direct Mount Chainring Info
The ethirteen Helix Race is a direct-mount chainring engineered for trail, enduro, and e-MTB riders who demand stiffness without weight penalty. Machined from AL-7075-T6 aluminum and built around ethirteen's 73mm Helix GR crank interface, it's designed to eliminate drivetrain slop and creep.
Key Features
- Direct-mount design for increased stiffness and a secure, creak-free connection
- Flip-flop reversible mounting to optimize chainline across different frame and hub spacing
- Compatible with SRAM and Shimano 12-speed chains
- CNC-machined AL-7075-T6 aluminum for strength and durability
- Hard-anodized finish available in multiple colors
Simple and purposeful. The Helix Race pairs seamlessly with other ethirteen drivetrain components, and its reversible design makes it easy to dial in the perfect chainline for your setup. A solid choice for riders building or upgrading a mixed 12-speed drivetrain.
