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.
