How do you count links on a bike chain?

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 chain is a serial assembly of connected pieces, called links, typically made of metal, with an overall character similar to that of a rope in that it is flexible and curved in compression but linear, rigid, and load-bearing in tension. A chain may consist of two or more links.

Count all the outer plates (including the master link), and multiply by 2. (Only on one side of the chain, of course.)

How do I know if my bike chain is too short?

You should also see two slight bends at each jockey wheel of the rear derailleur. If the chain is too short, this shift is difficult to make and the derailleur cage is stretched out and almost parallel to the chainstay. If the chain is really short, then you might not even be able to shift into the largest cog.

A master link or quick-release link is a roller chain accessory that allows convenient connection and disconnection of a chain without the need for a chain tool. It acts as a set of the chain’s outer plates, so joining two sets of the chain’s inner plate ends.

Begin by counting the number of teeth on the largest front sprocket and largest rear. These numbers are often printed right on the sprockets and cogs. Next, measure the distance between the middle of the crank bolt to the rear axle. This is also the chain stay length.

The chain is a unit of length equal to 66 feet (22 yards). It is subdivided into 100 links or 4 rods.

Twenty half-links in a new chain measure 10 inches (254 mm), and replacement is recommended before the old chain measures 101⁄16 inches (256 mm) (0.7% wear). A more conservative limit is when 24 half-links in the old chain measure 121⁄16 inches (306 mm) (0.5% wear).

What size chain is on a bicycle?

All modern bicycle chains are made to the “one-half inch pitch” standard, meaning from rivet to rivet is nominally 0.5 inches. The sprocket teeth are cut for this same one-half inch standard to accept bicycle chains. However, this does not mean all makes and models of chains are interchangeable.

How do I know what bicycle chain to buy?

If you are using a bike with a derailleur the number of cogs on the rear hub will determine the chain size you will need. They are always 3/32″ chains. You can get a 5/6/7-speed, 8-speed, 9-speed, or 10-speed chains.

How do I know what speed my bike is?

Multiply the front gear number by the rear gear number to get the number of speeds. For example, if you have two front gears and five back gears, you have a 10-speed bike. If you have one front gear and three back gears, you have a 3-speed bike.
