Advantages

1. 4mm Inward Offset for Better Chainline

The 4mm inward offset helps correct the chainline when converting from a 2x drivetrain to a 1x drivetrain.

This improves chain alignment, reduces drivetrain noise, and helps deliver smoother riding performance.

2. Narrow-Wide Tooth Design

The narrow-wide tooth profile is designed for 1x drivetrains.

It helps improve chain retention and reduces the chance of chain drop during riding.

3. Premium 7075-T651 Aluminum Alloy

Made from high-strength 7075-T651 aluminum alloy, offering excellent stiffness, strength, and durability.

This material provides reliable performance for road, gravel, and cyclocross riding.

4. Carbon Fiber Inner Spider

The carbon fiber inner spider helps reduce weight while maintaining a clean and high-end appearance.

5. High-Precision CNC Machining

CNC-machined with 0.03mm precision to ensure accurate fitment, stable operation, and smooth chain engagement.
