Christian, I've heard some people say the cup looks much like a Go Pro fixture
I looked up my photo equipment and found a suction cup that would fit. Not GoPro but it should work.
For the front mounting the following solution seems to be ok for me.
another talkmorgan solution These clamps can handle more than 30kg each that should be ok and no drilling is needed. Drilling the roll hoop won't be my cup of tea.
Maybe I will look for a nice replacement instead of the stainless eye bolt and rubber parts.
