I bought the Roswheel rear rack earlier this year for its construction, low price and especially the lower bar for panniers. Its form is excellent.

But it came with a manufacturing defect : the threads in the hole of one of the two little 'blocks' that recieves a screw on top were stripped for the length of the screw. The screws in both blocks are screwed in very tightly by the manufacturer and the hole is a bit too big for proper thread formation.



I replaced the screw with a longer one to get to undamaged threads, but you have to be careful since its length is limited by the secord screw in the same piece. The threads in the other block were in better shape and I consider the rack to be sufficiently safe for the time being, though I wouldn't go around the world with it. It's carried 30-40 lbs on gravel for hundreds of km with no problem.

Even with the manufacturing defect, due to nice design and low cost (nothing else as good for the price) I ordered another one for my daughter. It had exactly the same problem, which I took care of again. So I don't recommend this rack unless you're good at fixing things. And even then use locktite and a light touch.

Ortlieb sell a nice little kit E219 (~20$) that replaces the problem parts with much better quality with no work necessary.
