FAQ

Install it and forget about it is our mantra. Let's be honest: Nothing is more annoying than bike parts that let you down and require a lot of maintenance, because your time is precious and should ideally be spent on the bike. That's why we rely on a whole range of seals, which together with our special headset grease contribute to maximizing your good times in the saddle.  

This headset bearing kit includes the two bearings only. The compression ring is intentionally not included. Inspect your compression ring for signs of wear. If it is damaged or shows significant wear, we recommend replacing it at the same time as the bearings. Bicycle manufacturers often use bearings with the same dimensions across multiple models but differ in the other headset components. This also applies to the compression ring, which may vary in size and design depending on the model or headset specification. Use our bike selector to identify the correct compression ring for your bike. 

We develop and manufacture your headset to make it your loyal, inconspicuous companion. Nevertheless, like many other components on a bike, it is a wearing part. But you can combat wear and tear to maximize your worry-free time in the saddle through proper installation and care. Find our assembly instructions as a PDF download on the respective product page of your particular headset. By the way, we agree: high pressure cleaners are a great, time-saving affair. However, the strong water jet – often over 100 bar – is poisonous for your ball bearings because the high pressure can rinse out the grease. Even the best seals won’t help here if you’re not careful. Therefore avoid water blasting the area around the headset, but also around the bottom bracket and frame bearings. Apart from that, be careful around these areas with bike cleaners like Muc-Off. After all, these cleaners basically work as degreasers that will happily dissolve the grease in your bearings and, as a result, make them wear out much quicker. PS: Did you know that when having your bike on the car roof in the rain and at high speeds, is similar to cleaning it with a high-pressure cleaner? Accordingly, it is worthwhile to watch your max speed, cover your beloved bike and regularly re-grease your headset.  

Headsets are a complex component. With so many different standards and sizes, it’s not always easy to understand what you need. If you have any further questions, feel free to get in touch with us at any time. You can find the best way to reach us here
