OK so I've decided to get PJ1 lube and kerosene to take care of my gunked up chain.
Question: How do I know if I have an "O-ring. X-ring, or standard chain?" It depends on what type of lube I would need to buy. PJ1 Blue (o-ring and x-ring) or Black (standard/ non o-ring) can.
If possible can you post a pic of a chain?
