How to Adjust the Gears on a Mountain Bike: A Step-by-Step Guide
To adjust the gears on a mountain bike, first shift the chain to the smallest chainring and the largest rear cog. Then, use the barrel adjuster to align the jockey wheel of the derailleur with the first cog. Next, shift the chain to the largest chainring and the smallest rear cog, and adjust the high limit screw until the jockey wheel lines up with the last cog. Finally, use the barrel adjuster to fine-tune the shifting between gears. Repeat the process for the front derailleur.
