The Stone 110BCD 5-bolt round chainring is designed for riders who want to convert their road or cyclocross drivetrain from 2x to 1x.
This chainring features a 4mm inward offset, helping correct the chainline after converting from a double-chainring setup to a single-chainring setup.
The narrow-wide tooth profile improves chain retention, making it a reliable choice for 1x road, gravel, and cyclocross builds.

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.
