QYAAUPMMP 130 BCD Chainring Ultralight Narrow Wide Teeth 46T 48T 50T 52T 56T 58T Single Sprocket Hollow For Folding Bike(50T silver)
- Universal 130 BCD Compatibility：Direct-fit replacement for 5-arm 130mm bolt circle diameter cranksets, compatible with folding bikes requiring 46T to 58T tooth configurations for single-speed drivetrain optimization.
- Ultralight Hollow Structure Design：CNC-machined from aerospace-grade 7075-T6 aluminum with hollow sprocket architecture, reducing rotational weight by 35% while maintaining structural rigidity for efficient power transfer.
- Narrow-Wide Tooth Retention Technology：Patented alternating tooth profile secures the chain during high-vibration riding, preventing derailments on folding bikes without requiring chain guides or additional hardware.
- Multi-Terrain Debris Clearance：Chamfered tooth roots and optimized gaps actively shed mud, sand, and road debris, ensuring consistent performance in urban commuting or gravel paths.
- Tool-Free Installation System：Precision-machined bolt holes with alignment notches enable quick mounting on standard 130 BCD cranks, reducing installation time to under 10 minutes with basic hex tools.
