Have bought me the porter (for my mountain bike), because he seemed quite flexible since the front (on the screen already) was already evident that the front support pins were individually adaptable (it should be so, since it is a Universal Rack). At least the front was fixing a problem. In addition, it should still be relatively stable, which I doubted at first. One problem was that I had the frame down only a single screw hole for mounting. The accessory was for both sides here. Only the lateral holders could be more flexible. The one can indeed move downwards, but not sideways. Is it possible in part by high or fold down the luggage carrier offset, but only conditionally. When everything was screwed, I made the strength test and found that everything is very stable and does not wobble. This part is highly recommended. Especially at this silly price. PS I could even with an additional sheet that came together in the delivery, the fender lying down, which had me already so annoyed because it is always folded down, could fix the rack.
