Nope. Old bikes, with no masterlink.
Either chains with no ID marks , or ones that don't reference on search.
no problem with anything I have bought, I usually keep any extra chain wrapped in the bag it came in
and they usually have stamped ID on the chain.
Assuming a chain size based on the gears of an old bike is not really more than a guess, and guessing is a more problematic approach.
This is for Sound chains that I am removing to clean or shorten, mostly, often with no Masterlink
or wanted spares for the tool pouch to carry and take from bike to bike.
I also help others rebuild old bikes , where their heritage is not known.
