How do I know what chain to buy for my mountain bike?

A lot of mountain bikes are 10-, 11- or 12-speed and, when buying a chain, it will be clearly labelled accordingly. Simply find out how many gears, or ‘speeds’, you bike has (count the number of gears on the rear cassette and multiply it by the number of chainrings at the front), and pick the corresponding chain.
