FSA Mallet Headset

This headset is designed for a standard 1.125-inch steerer tube. Before purchasing, verify that your fork's steerer tube matches this diameter, as it will not fit tapered or oversized steerer tubes.

The Mallet is built with more robust materials and seals than standard road or light-duty headsets. It is specifically engineered to handle the increased stress and vibration common in aggressive riding styles, such as mountain biking or heavy commuting.

Yes, this is a threadless headset designed for modern stems that clamp directly onto the steerer tube. It is not compatible with older threaded forks that use a quill stem.

Yes, installing this headset properly requires a headset press to seat the cups into the frame and a crown race setter to seat the race onto the fork. If you do not have these specific bike tools, a local shop can handle the installation quickly.

While the construction is durable, the service interval depends on your riding conditions. If you frequently ride in wet, muddy, or dusty environments, you should inspect and re-grease the bearings at least once or twice a year to maintain smooth steering.
