Star nuts and caps

Shop navigate_next Components navigate_next Headsets navigate_next Star nuts and caps
The star nuts and their caps are essential components that play a key role in the installation and adjustment of the head assembly on your bike. The star nuts are inserted into the neck of the fork and provide an anchor point for the top bolt. The upper cap, on the other hand, helps to secure the headset and, together with the star nut, serves to set the correct bearing preload.
