The headset is the component that causes the fork to wiggle in the bike's headphones, so it's important to keep it in good working condition and replace it if necessary.
When it comes time to look for something new, you'll find that there are many different types.
When should I change my headset?
The bike's headset consists of two layers, one mounted on the top of the main tube and the other on the bottom. Let the fork and front wheel turn.
Bearings can fail over time, especially if water and dirt can penetrate. Due to its location near the front wheels, the lower layer of the headset is particularly prone to getting wet with any problems that may be caused by metal objects.
It is clear that the headset is not working properly. Turning the steering wheel can rub it or look rough and dirty. Sometimes, you may feel a bit of a problem when using the front brake or turning the bike back and forth with the brakes on.
Some headphones are useful. You can open the headphones and organize, fill and adjust layers. Even with them, you can gently tear the seal, clean the interior and add new grease, but in case of backlash (unnecessary removal), it's time to get a new one.
Wireless headset
Unlike traditional threaded headphones, headless threaded headphones do not have a top lock nut that can be secured to the threaded fork shaft. The cover on the top of the guide is used to preload the bearing. The bolt in the center of the cover tightens the screw to the device inside the steering gear of the fork, pulls everything together and then tightens the bar to hold the headset in place.
Threadless headsets have been mainly used in threadless headphones in recent years. They're easy to install, don't hang on uneven surfaces, and the fact that the main tube doesn't require any thread means it can be made from carbon fiber on more expensive bikes.
Other bikes fit different types of headphones without a thread. There is no universal alternative.
Nowadays headset bike bearings are usually inside the power source. Sometimes the bearings are made of copper (semi-integrated or internal), which requires a certain type of headset, and sometimes cartridge bearings are mounted directly on a special main tube shape (integrated system). You'll need headphones without copper.
Another thing to remember is the size relative to the outer diameter of the steering fork, which can be easily measured with a ruler.
Unthreaded headphones work with a bar that grabs the fork end, rather than a bar that slides right into the handlebar. Legs are available in a variety of lengths and angles, which can improve your fit.
