How to Tighten Bike Chain on Mountain Bike: A Comprehensive Guide
To tighten the bike chain on a mountain bike, start by shifting the chain onto the smallest chainring and smallest rear cog. Use a chain tool to remove any excess links, then adjust the rear derailleur so that the jockey wheel is in line with the smallest cog. Use the barrel adjuster to fine-tune the tension of the chain and ensure it is not too loose or too tight. Check the chain tension by lifting the chain at the center of the cassette. Once the tension is correct, reassemble the chain and test ride to ensure everything is working properly.
