Hello, after the tip now here in the forum I decided for a “17-44-112 DID530ZVM-X(G&G) Niet”. Dry Lub is used as a lubricant. As far as possible. Before Dry Lub can be applied, the chain has to be cleaned, i.e. fat-free. If you are looking for “O-Ring or X-Ring chains clean” you will quickly find out that everyone tells something else. My personal favorite would be a small tub with washing spirit, chain pure, clean with bristle brush, half stun Let it dry – done. It is however to read the gasoline attacks the seals. What does this look like with washing gasoline? Shouldn’t washing gasoline be the right one, what does it look like with chain cleaner? Is there a product recommendation here? Thank you for your effort.
