The tool I have is the Suntour NWN which I thought, after the the first few posts, was the correct tool.
It turns out it is a freewheel adjustment tool.
After reading additional posts to this thread it turns out I DON'T have the correct tool.
ARRRRRRRGH
Sorry
Old guy trying to be helpful mistake.
After rooting around my tools I found another Suntour tool that I have no idea if it will work.
The search continues.
This is the other Suntour tool I found and I am NOT sure it will be helpful to you.



The business end
