Colin - The reusable weights look interesting. Not sure I could tolerate the look though, but I'll save the link.
This was the factory fix - when I first got Bumble and cleaned the wheels up. It's hard to see here but the inner rim is contoured, the flat area is quite narrow.
This shows the outer rim at the same time, different wheel.
You can see there's no flat rim area, and the two weights at 9 o'clock when painted black, don't look too bad.
