FSA Campy Freehub

This freehub is engineered specifically for FSA Metron SL, Trimax KB, and Trimax KOM wheelsets. It will not fit other FSA hub models, so please verify your wheelset model before purchasing.

No, this specific part is designed for Campagnolo 10 and 11-speed cassettes only. It is not compatible with 12-speed systems due to differences in cassette spacing and spline design.

Installation typically requires standard hub maintenance tools, such as cone wrenches or hex keys, depending on your specific hub configuration. If you are comfortable with basic drivetrain maintenance, it is a straightforward swap, but we recommend consulting your wheelset's service manual for the exact procedure.

This alloy construction is chosen to keep the overall weight of your wheelset as low as possible, which is critical for high-performance riding. While steel is heavier, this alloy version is built to be robust enough to handle the power transfer demands of competitive cycling.

You should consider replacing your freehub if you notice excessive play in the cassette, grinding noises while coasting, or if the pawls are failing to engage properly. If you feel skipping or hesitation under load, it is likely time for a service or replacement.
