Suntour rear shock supplied by R&M. This is the replacement (#2 above).
With the front shock (fork), everything is on show; by contrast, the rear shock is hidden.
As far as I am aware, Riese & Müller are well aware of the problem and are standing by their customers (their dealers); however, it took me a while to realise that replacing Suntour with Suntour was not the solution.
In fairness, it needs to be added that I have had no problem with the rear Suntour shock on my 2019 Homage Rohloff (30,000 km). It is Suntour? Someone correct me if I'm mistaken—it's 99% out of sight.
