Derailleurs

Bike derailleurs are essential components that manage gear shifting on multi-speed bikes.

They move the bike chain between different sprockets or chain-rings, allowing the rider to adjust pedalling resistance.

Front derailleurs shift the chain across the chain-rings, while rear derailleurs handle the cassette at the back.

Modern derailleurs come in both mechanical and electronic versions, offering precise shifting for various terrains.

Derailleurs are matched with the amount of sprockets on your cassette. So if you're cassette has 8 sprockets, a 10-speed front or rear derailleur won't work.
