SEALED HEADSET BEARINGS

We stock a very comprehensive range of headset bearings, many of which are specific to a bike brand. It can be quite tricky to determine the actual bearing you need, but if you remove your bearing that needs replacing you can quite often determine the bearing you require by taking a few measurements. Each bearing we sell has listed an inner diameter, outer diameter, depth (in mm) and chamfer angles in degrees. If it is specific to a brand we will give further guidance in the listing too. We have quite a comprehensive range of independent bike dealer stockists of our headset bearings, so if in doubt we recommend you go to your nearest stockist where you will be able to try for size.
