How to Efficiently Replace Bike Chain on Your Mountain Bike
To replace the bike chain on a mountain bike, first, remove the old chain using a chain breaker tool. Measure the length of your old chain and cut the new chain to the same length using a chain breaker tool. Next, thread the new chain through the derailleur, cassette, and chainring, and connect the ends of the chain using a quick-link or a chain pin. Finally, adjust the chain tension and shift the gears to ensure everything is working correctly.
