Product Description: Chain size is 415H x 110 links (55 Inches) long (55 outer plates).
Frames for single speed bikes, if no chain tensioner is used, usually have rear dropouts that allow moving rear wheel back and forth – so that correct chain tension can be achieved once the chain is cut to size. One chain link is exactly one inch long.

Surveyors’ chain (Gunter’s chain)
In 1620, the polymath Edmund Gunter developed a method of accurately surveying land using a 100 link chain, 66 feet long called the Gunter’s Chain. Other surveyors chains have been used historically.
One link is two pin-to-pin dimensions. Each pin is 1/2″ from its neighbor, so a full link is 1″ long. When they say the chain is 116 links, they are really saying there are 116 pins, for a chain length of 58 inches.
A new bicycle chain usually comes with 116 links. This is long enough for the biggest chainrings and for most distances of rear wheel from front chainrings.
How do I know my bike chain size?
The method of chain sizing depends upon the range of gearing in the system. For bikes with rear sprockets 36 teeth and smaller, the common system is to measure using the largest rear sprocket and largest front ring as a reference. Two rivets are added to this (one-inch) for the place to cut the chain.
Are all bicycle chains the same size? No, all bicycle chains are not the same size. Size varies on the bike’s numbers of sprockets, speeds, the distance between the front chainring and rear cogs, and the number of teeth on them.
Generally 6-7-8 speed chains are the same and 9 speed are thinner, more than 9 speed is a bit specialized. The length isn’t as important because you will usually have to shorten the chain to fit your bike. The standard chain is 114 pins (56 links) but you almost never need to know this ( I had to look it up!). Aha.
Are bike chains universal?
A number of different chain widths are available, to suit specific bike types such as BMX, or to fit different road and MTB drivetrains (e.g. an 11-speed cassette requires a different chain to a 9-speed one – the chain must be thinner in order to fit into the narrower spaces between the sprockets.
How long is a Gunter’s chain?
Invented by the English mathematician Edmund Gunter in the early 17th century, Gunter’s chain is exactly 22 yards (about 20 m) long and divided into 100 links. In the device, each link is a solid bar.
The 30 m chain is divided into 150 links. So, each link is of 0.2 m. The tallies are provided after every 25 links (5 metres).
