Stone 110BCD 5-Bolt Round Chainring with 4mm Inward Offset for 1x Conversion – Narrow-Wide 9–12 Speed, Carbon Spider, Fits Rotor, FSA, Sigeyi, Xcadey & QUARQ (42–60T)
The Stone 110BCD 5-bolt round chainring is designed for riders converting a road or cyclocross drivetrain from 2x to 1x.
Its 4mm inward offset helps correct the chainline after switching from a double-chainring setup to a single chainring, improving alignment and reducing drivetrain noise.
The narrow-wide tooth profile enhances chain retention, making it a dependable choice for 1x road, gravel, and cyclocross builds.

Advantages
1. 4mm Inward Offset for Better Chainline
The 4mm inward offset corrects the chainline when converting from a 2x drivetrain to a 1x setup. This improves chain alignment, reduces drivetrain noise, and delivers smoother riding performance.
2. Narrow-Wide Tooth Design
The narrow-wide tooth profile is designed specifically for 1x drivetrains. It improves chain retention and reduces the chance of chain drop while riding.
3. Premium 7075-T651 Aluminum Alloy
Made from high-strength 7075-T651 aluminum alloy for excellent stiffness, strength, and durability—reliable performance for road, gravel, and cyclocross riding.
4. Carbon Fiber Inner Spider
The carbon fiber inner spider reduces weight while maintaining a clean, high-end appearance.
5. High-Precision CNC Machining
CNC-machined to 0.03mm precision, ensuring accurate fitment, stable operation, and smooth chain engagement.
