The thread for the disc brake mount on my bike was defective. It was accepted as a warranty case. However, the processing took a good six months. Since I assumed I wouldn't get a new fork anymore and wanted to ride during the summer, I bought one from 8bar. See photo with the original Grandurance Expert. Now, towards winter, I suddenly received a new fork in the mail. But I don't feel like rebuilding it again. Attention: On this fork, the cone for the Acros headset is laminated directly into the steerer tube. I don't know if this fits other bikes.
