Hi, after around 200 km with rack I can truly say that Working well. But dosn't fit all of the bikes. You have to ride always carefully and watch your rack if not moving out the last problem is that one of the tack it's slightly bend from the hits on bicycle.
I have a touring bike and the rack mounts don't fit. Description of the product should include accurate mesures. I just thought it would be a standard. Very disappointed with this product. No problems whatsoever with the seller and or delivery times tough.
