Rear derailleurs
Rear derailleurs are an integral part of a bicycle's drivetrain, responsible for moving the chain between different sprockets on the cassette to enable smooth gear shifting. Cyclists, whether amateur or professional, rely on rear derailleurs to achieve optimal performance on varied terrains, from flat roads to steep climbs. They ensure swift and precise gear changes, allowing riders to maintain cadence and exert power efficiently during their rides.
When choosing a rear derailleur, two critical factors are cassette compatibility and cage length. Cassette compatibility typically indicates the number of gears the derailleur can shift between, with 12-speed cassettes being a common option that enhances gear range for challenging rides. Cage length, described as either short, medium, or long, influences chain tension and capacity; a long cage is ideal for handling a wider range of gears, making it a popular choice for mountain and gravel bikes. Filtering by these properties will help you find a rear derailleur that functions seamlessly with your bike's existing setup and meets your gearing needs.
