Hello Christian, I see it exactly the same way, 71cm cannot be. I also come to 79 cm after my own measurement. But if the board fits, the desk is a joy to use, I can highly recommend it.

According to measurements on my own table, it should be 798mm. (Unfortunately, the frame is already installed, which is why I could not test the operation with this width, but purely from the structure of the frame it should fit. According to measurements, the minimum length of the "drive shaft" would be approx. 620mm, that of the supporting frame 798mm, so I would assume the limiting factor there) The 71cm according to the technical details are certainly not correct.
