I am quite impressed by the stand and it's a lot of work to work on a bicycle, which can be positioned in such a way as you would like, and that you both standing and sitting can work. I do not want to deal with the little things that others have noted, and that could be improved. For the money, the sub-OK, and works as it should. But (and therefore "only" 4 points): you should already well aware that is exactly specified in the product description that the inclusion of the framework is made up to 4 cm thickness. It is not suitable for so-called "Banana MTB", and all other frames that consist of very broad and oval in cross-section tubes. I attach my MTB now forced to the pipe, where the seat post is inserted. This works well, but I have no chance to balance the wheel horizontally. Do I need but not necessarily. When I work behind the wheel, I let the front wheel just lean on one of the tripod legs (the wheel has Übergewich forward). If I want to work at the front, I put a box or my little bench under the front wheel. And everything is OK. The bar for Festhaltebn the handlebar can be incidentally prima connect with the seat post of the bicycle instead of the center tube of the tripod. This can be the whole wheel turn loose and position as you like. The product image here at Amazon is the way chosen very unfavorable, one might think that the tripod is three-legged, but it is not. There are four legs. The one can even, if you want it, at the prepared holes in the feet firmly to the subfloor eg by connecting plugs.
------------------------- Addendum: against twisting of the MTB I simply attached a few holes through the plastic and the tubes of the holder and created with simple screw hooks stability against twisting due to the problem with the imbalance Remedy. The holder I now bring directly to the seat post itself, which avoids scratches on the frame. Just awesome. Nevertheless, I go by the 4 points down to 3 because 1) the manufacturer also could have it, and 2) I have gambled through the holes any right of return.
