Reading the size
A chain size such as 520 is two measurements. The first digit is the pitch, the distance between pin centres, counted in eighths of an inch: a 5 means 5/8 inch.1
The last two digits are the inner width between the plates, also in eighths of an inch: 20 means 2/8, which is 1/4 inch (6.35 mm). So 520, 525 and 530 share a pitch and differ in width.2
Chain length is counted in links. The stock count for each bike is in the table above where a manual prints it; if you change sprockets, the chain length calculator works out the new count.
Before you order
Match both numbers: the size (pitch and width) and the link count. A chain of the right size but the wrong length cannot be adjusted into place.
Replace the chain and both sprockets together. The chain maker D.I.D advises changing them at the same time.3
When to replace it
D.I.D recommends replacing a sealed (O-ring or X-ring) chain at 1% elongation and a non-sealed chain at 2%. Pin heads that have started to rotate, rust, stiff links or missing seal rings are also signs it is time.3
