Troubleshooting

Pros and Cons

Pros

  • High-grade steel offers superior durability compared to standard aftermarket parts
  • Cost-effective alternative to expensive OEM components
  • Direct fitment requires no modifications to the drivetrain
  • Professional factory aesthetic enhances bike appearance

Cons

  • Requires specific 520 pitch chain for correct installation

  • Steel construction is heavier than aluminum alternatives

Setup, Compatibility & Care

Installation should be performed while the bike is on a stable stand. Ensure the bike is in neutral before removing the front sprocket cover. Always verify that your chain is a 520 pitch before installing this sprocket; mixing pitch sizes will cause immediate failure. To maintain the life of your sprocket, keep your chain clean, properly tensioned, and lubricated according to your bike manufacturer's service manual. Periodically check the teeth for 'hooking' or wear; if the teeth begin to show a shark-fin shape, it is time to replace both the sprocket and the chain to ensure safety and performance.
