How to Properly Tune Gears on Your Mountain Bike for a Smooth and Efficient Ride
To tune gears on a mountain bike, start by shifting the bike into the hardest gear, and ensure the chain is on the largest rear cog. Then, use the barrel adjuster on the rear derailleur to align the jockey wheel with the cog. Next, shift into the smallest gear and make sure the chain sits on the smallest cog. Use the barrel adjuster to align the jockey wheel with the smallest cog. Repeat the process for the front derailleur, ensuring the chain stays on the chosen cog. Finally, check and adjust for chain rub.
