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 link do I need for my bike?
If your bike is equipped with the derailleur, you need a 3/32′′ or 11/128′′ chain
. If you have a single-speed or internally geared bike, you need either 1/8′′ or 3/32′′. You should get the correct size, but if it is not possible, you can get the 1/8′′ because it has limited compatibility with the 3/32′′ sprocket.

What size chain is bicycle chain?
Chains come in 3⁄32 in (2.4 mm), 1⁄8 in (3.2 mm), 5⁄32 in (4.0 mm), or 3⁄16 in (4.8 mm) roller widths, the internal width between the inner plates. 1⁄8 in (3.2 mm) chains are typically used on bikes with a single rear sprocket: those with coaster brakes, hub gears, fixed gears such as track bicycles, or BMX bikes.
How do you measure the width of a bicycle chain?

- Inner chain width, marked with blue arrows and lines.

How long should a chain be?
After a measurement is obtained, its a good idea to opt for a necklace size that is
at least the second size up from your neck size

58 inches
.
Are all bike chain links the same size?

The digits to the left indicate the pitch of the chain in eighths of an inch

How do I know what size bike chain to buy?
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
