The new replacement chain that just came in for my Rans Stratu a K9000 came with the replaceable link included. I can see why as the link pins in the chain has really large flairs. In fact I had to remove the pins from each end to get rid of the outside side plates. These pins were very hard to remove as the flange had to break off to get the pin out. In no way could I see if one of those pins were reused would the chain be as reliable as it was. I have been using the removeable links since 2005 and they work without any trouble at all. They make it easy to remove the chain for cleaning. One other small advantage is they make a start and stop place when oiling the chain. I carry a new replaceable link in case of breakage on my bike or who I might be riding with.
