How to effectively replace gears on a mountain bike
Replacing gears on a mountain bike involves several steps. First, remove the old gears by unscrewing the bolts holding them in place and removing the cassette. Next, fit the new gears onto the cassette, lining up the teeth with the chain, and tighten the bolts in a crisscross pattern. Finally, adjust the derailleur to ensure smooth shifting between gears. Be sure to follow manufacturer instructions and use the appropriate tools for each step of the process.
