How to Properly Tune Your Mountain Bike Gears for Optimal Performance
To tune mountain bike gears, start by ensuring that the bike is clean and that the cables and housing are in good condition. Shift to the middle gear on the rear cassette and the middle chainring on the front. Then, adjust the barrel adjuster on the rear derailleur until the chain jumps smoothly onto the next gear. If the chain won’t shift onto the largest or smallest rear gears, adjust the limit screws on the derailleur. Finally, fine-tune the alignment of the derailleur using the H and L limit screws. Repeat these steps for the front gears, if necessary.
