Bike Derailleur Components at L9 Sports
Whether you are building your own bike to your personal specifications or you are needing to replace a bike front derailleur or a bike rear derailleur because of wear and tear, L9 Sports has the bike derailleur parts needed to create a precision shifting experience. We have a fantastic selection of road bike derailleurs and mountain bike derailleurs from which to choose in several sizes — including short, medium and long.

Road Bike Derailleurs and Mountain Bike Derailleurs
Your bike has both front and rear derailleurs, which are the devices that move your bike’s chain between the cogs. Derailleurs determine your ratios: the highest ratio (when your bicycle goes the fastest) occurs when the chain is on the biggest sprocket in the front and the smallest in the back. The lowest ratio (when the bike is easiest to pedal yet is very slow, as in up hills) occurs when the chain is on the smallest sprocket in the front and the biggest in the back.
