How to Tune a Derailleur on a Mountain Bike: A Step-by-Step Guide
To tune a derailleur on a mountain bike, start by checking the derailleur hanger alignment and tensioning the derailleur cable.

Finally, fine-tune the indexing by adjusting the barrel adjuster until the chain smoothly transitions between gears. It may take some trial and error, but with some patience and practice, anyone can tune a derailleur on a mountain bike.
