There is a problem with the design of cable routing in the rear bottom pivot area. The cables/hoses are rubbing against the pivot bolt. I noticed it today. The bolt itself will probably survive till the end of life of the bike, but the brake hose will not. Be careful people cause it may damage the rear brake hose and that can lead to an accident, injury or worse. In many different models of different companies there is a special swivel at this area that prevents rubbing. Here nothing like that is to be found.
