Vivian replied: Of course, that's not covered under warranty, since I would have damaged the threads... The fork threads don't look very good anymore either. I always tightened the axles by hand and then with a torque wrench. It's simply cheap material quality. That's definitely it for me, and I can only warn everyone against buying from them. Regarding the scratched top tube, she already said I was just unlucky, even though it was clearly a defect in the top cap.

Unfortunately, after a year, I can no longer recommend this frame and must warn against buying it. It started with a scratched top tube due to poor workmanship (a now well-known problem). Today, I couldn't tighten my rear wheel with a torque wrench because the threads are so worn (very poor material quality). I always screwed the thru-axle in by hand and then tightened it completely with a torque wrench. So it wasn't an assembly error. The frame is now scrap and I have to throw it away. It was a very expensive mistake for just one year of use. I contacted Vivian at TanTan and am still waiting for a reply. However, I'm not very optimistic.

Hi,
I have a question before I shorten the fork. Do I have to leave the fork 5.5mm shorter than the top of the stem to be able to adjust the headset? That seems to be a lot. Am I making a mistake?
