The headset does an important job and you’ll know about it if it’s not working properly! Your bike headset allows the fork and front wheel to turn properly. It’s important to replace your headset if it’s damaged, as it could impair your steering or even damage your bike frame. There are different types to look out for including integral, internal and external. If replacing your headset ensure that it matches your head tube and fork crown – many modern road and MTB bikes feature tapered head tubes that flare out to a wider diameter at the bottom, so your headset will need to be compatible.
