Origin8 Blade Chainring

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

No, this chainring is specifically engineered for 8-speed and 9-speed drivetrains. Using it with higher-speed chains may result in poor shifting performance or chain retention issues due to the difference in chain width.

6061-T6 aluminum is a heat-treated alloy that provides an excellent balance of high strength and low weight. This makes the chainring durable enough for daily riding while keeping the overall mass of your drivetrain down.

The anodized finish is highly durable and corrosion-resistant, so it does not require special treatment. Simply clean it with standard bike degreaser and water as part of your regular drivetrain maintenance routine.

No, this product includes only the chainring itself. You will need to reuse your existing chainring bolts or purchase a new set compatible with your specific crankset.
