Derailleurs Derailleurs are vital for smooth gear shifting. Choosing the right one depends on your bike’s drivetrain (front or rear) and speed compatibility. Consider clutch mechanisms for mountain bikes to reduce chain slap and keep your chain secure on rough terrain. For road bikes, prioritize lightweight derailleurs with precision shifting. Regular maintenance can extend the life of your derailleur and ensure optimal performance. Planet Cyclery offers a range of high-quality derailleurs to keep you shifting smoothly.
