How to Change a Chain on a Mountain Bike: A Step-by-Step Guide
To change a chain on a mountain bike, first shift the bike into the smallest chainring and smallest cog. Use a chain tool to break the chain, and remove it from the bike. Thread the new chain through the derailleur, around the cassette, and onto the chainring. Connect the ends of the chain using a chain tool, ensuring that the link pins are fully seated. Finally, check the tension of the chain and make any necessary adjustments.
