I am going crazy here. I have a SA SRF3 mounted on a 16 inch wheel Dahon bike I bought second hand. The bike needed some love and I managed to put it to my liking. Unfortunately I reached a dead end with the SA hub. I am on my 50th attempt of setting up the the damn thing, I looked at countless online manuals and tip and tricks. There’s no way to know I have the right tension on the chain as I pull on it to the max and never see the start of the indicator rod, is it possible it’s too short? Or is there another way to adjust it? I am willing to buy an indicator rod but how to know the right length?
Thank you in advance for any help you can provide me
