I've used the Tubus Tara for several tours. Is is a sturdy straight forward rack. It is easy to mount and folds flat, if it has to come off when boxing the bike for shipping. It is easy to squeeze it into the box with the bike
I have hundreds of pictures of the rack loaded, but you can't see the rack. This is one of the few I have of the bare bike. I was taking advantage of a campground's hose and water to clean the bikes while on a tour.
