FSA PowerBox Chainring

This chainring is specifically engineered for FSA PowerBox systems. While it features a standard 110mm BCD 4-bolt pattern, you should verify that your specific power meter spider allows for the asymmetric mounting required by this design.

The carbon construction significantly reduces rotational weight compared to traditional aluminum rings, which helps with acceleration. It also provides a high stiffness-to-weight ratio, ensuring that your power transfer remains efficient during high-wattage efforts.

The 110mm BCD is a versatile standard that accommodates a wide range of chainring sizes. While this specific model comes with 53 teeth, the bolt pattern allows you to swap to smaller or larger rings in the future, provided they match the 4-bolt asymmetric configuration.

While it is built for road cycling, the durable carbon construction can handle varied road conditions. However, it is optimized for road-specific drivetrain setups, so ensure your current derailleur and chain configuration are compatible with a 53-tooth ring before installing.

You will need a standard set of hex keys or Torx wrenches to remove your existing chainring bolts. Because this is a carbon component, we strongly recommend using a torque wrench to ensure you do not exceed the manufacturer's tightening specifications.
