Origin8 Alloy Chainrings

Non-ramped chainrings lack the pins and shaped teeth designed to help the chain move between rings. This means they are best suited for single-ring setups or track bikes where you aren't shifting between gears, as they provide a more direct and secure chain engagement.

This chainring is designed for a standard 130mm BCD (Bolt Circle Diameter) with a 5-bolt configuration. Before purchasing, verify that your crankset matches this specific bolt pattern to ensure a proper fit.

No, this chainring is specifically engineered for 8, 9, and 10-speed drivetrain systems. It is not optimized for the narrower chain width required by 11-speed or 12-speed setups.

6061-T6 is a high-strength aluminum alloy commonly used in cycling components for its excellent balance of weight and durability. It is robust enough to handle standard daily riding demands while maintaining its shape over time.

The black anodized finish is chemically bonded to the aluminum, making it significantly more durable than standard paint. While the silver CNC-machined teeth will naturally show metal where the chain makes contact, the main body of the ring will retain its color well.
