Both the revolution and the x-tools stand have the same Y base as the Minoura RS5000, which is more expensive and has a better clamp.
The Minoura is ok for lightweight work only – the base is not stable enough and will tip over easily, for example if you take one of the wheels off the bike.
If you put weighty sand bags over the legs it might be ok.
I had a cheaper stand and junked it for a Minoura. I then gave the Minoura away and bought a Feedback – I should have bought the Feedback in the first place instead of wasting money on the other stands.
