Cannondale Formula Freehub Body FH-513

The FH-513 is a specific replacement part designed for select Cannondale hubs using the Formula system. You should verify your existing hub model or check the part number stamped on your current freehub body to ensure it matches KP488.

No, this specific model is engineered for 11-speed drivetrain systems. Using it with other cassette speeds may result in improper spacing, poor shifting performance, or damage to the drivetrain.

Yes, replacing a freehub body typically requires a cassette lockring tool, a chain whip, and often a hex key or cone wrench to remove the axle assembly. If you are not comfortable servicing your hub bearings or drivetrain, we recommend having a professional mechanic perform the installation.

While not strictly required, it is often a good idea to inspect the hub bearings while the assembly is apart. If you notice any grittiness or play in the hub, replacing the bearings at the same time is a smart way to restore your wheel's performance completely.

You likely need a replacement if you experience skipping under load, excessive play or wobble in the cassette, or if the pawls inside the freehub are failing to engage properly, causing the pedals to slip.
