How to cut a bike chain for proper sizing and installation?

To cut a bike chain for proper sizing and installation, you will need a chain tool specifically designed for bikes. First, determine the correct length of the chain by wrapping it around the largest front chainring and the largest rear cog without going through the derailleur. Use the chain tool to push out one of the pins at the appropriate link to shorten the chain to the correct length. Reconnect the chain using the chain tool to press the pin back in place. Make sure the chain is properly installed and lubricated before riding.
