It's difficult to tell from the photo but I don't think that's the same stand as I bought a couple of years ago from Lidl or Aldi.
The base on mine seems to spread much further than the one in the pic although, as I said, it's hard to see it properly. As far as mine is concerned, it supports my rear hub-driven Kalkhoff in spite of the inherent imbalance with such bikes. I can even hand-pedal to quite a high speed with the bike on the stand which is useful when fettling derailleur gears. It has never twisted away from the near horizontal position under such load and has never broken free from the clamp. The fulcrum for clamping of course is critical.
A decent stand really is a boon when working on bikes and the doubts I had about the stand's ability to cope with an offset load of a smidgin over 21Kgs were soon forgotten. Having said all that, I never raise my bike to the height of the Cannonade in the picture as I tend to sit while doing many of the tasks but even when standing, I don't need the bike too far off the ground. Whether or not that's anything to do with the fact I'm only 4'-9", I can't be sure.
