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.

The brake pads included with one of the two calipers were unpacked, visibly already installed on a bike somewhere, and the spring was missing, but I used the old one so it didn't bother me too much; someone else would have a problem if they didn't have the spring. I only order from MTBIKER and will continue to do so, I am satisfied. Small mistakes always appear, and not only here. So I recommend the shop.

Helpful shop assistant, I ordered a smaller glove size, there was no problem changing the order to a larger size. He also advised me to try the goods on, for which I am grateful.
