Sedis chain, hailing from France and in production from the 1970s to the 1980s. Made from steel and weighing in at 349 grams. A fine choice for keeping your vintage bike authentic, but also great for any other compatible bike too.
The chain's been examined for wear, thoroughly cleaned and degreased, then freshly lubricated and graded as good condition, but do take a good look at the detailed photos so you can see the cosmetic condition before you buy. Chain stretch for this one comes in at 1/32” (around 25% worn), measured by hand as this is the most accurate method, and although it’s impossible to be exact it gives a good indication of how much use a chain has had.Please consider that chains do wear at the same rate as the sprockets they were originally used with, and when partnered with different ones they can on rare occasions skip. This can usually be avoided by using compatible sprockets with a similar amount of wear as the chain, but there is no way for us to confirm which combination will work before trying.

▼HELP SECTION

Speed - the number of cogs at the back the chain was designed to be used with.
Compatibility - the brand and/or shifting system the chain is compatible with. Universal means the chain can be used with any standard shifting system, as long as the speed and width are correct.
Chain width - the gap between the inner plates where the chain sits on the sprockets. 3/32" has been standard for bikes with derailleur gears since the mid 1900s. When 9 speed was introduced the spacing reduced slightly but if the speed & compatibility are correct this isn't something you need to pay attention to. Single speed, track & BMX bikes will require either a 3/32" or 1/8" chain depending on the width of the rear sprocket and/or chainring. There's also a much wider 3/16" moped chain which can be used as a heavy duty chain for bikes without gears if required.
Chain pitch - the distance between the rollers (the cylindrical parts that roll around the pins). Pretty much every bicycle chain will be 1/2", the only time you will need a different pitch is for very early track bikes that take a 3/16" chain (also known as 'inch pitch'), or Shimano's short lived 10 mm pitch system from the 1970s/80s.
Number of links - the total number of links in the chain. If you're unsure how many links you need, you can measure your old chain (or a bike with a similar setup to yours).
