Hey guys another question for the knowledgeable.
I have a NIb Sachs Aris freewheel. No markings regarding threading or labeling on the box. Also couldnt find any online info on signs of what the threading might be.
So trial and error, i very very gengly screw it on a few hubs that all have perfect threading. The thing screws on french, italian, and english freewheels with no resistance and dainty pressure.
I know ISO will fit bsc and italian but whats up with the french threading working. There was no resistance and it felt like good solid fit with all 3. i inspected the threading on all when done and no change or damage. obviously teh freewheel itself is steel-so nothing there.
Anyone care to shed light on this.
bestest regards. Barry scott
