A cassette is an essential part of a modern bicycle's gear system, located on the back wheel. It's a collection of different-sized sprockets (toothed wheels) that work with the bike chain to make pedaling easier or harder. When someone mentions "cassette" in a bicycle repair context, they're referring to this gear component, not the music storage device. This part is crucial for any bike with multiple speeds, from basic commuter bikes to high-end racing bicycles. Other terms you might see used are "rear cogs," "sprocket set," or "gear cluster."
