Relatively small in stature, front derailleurs have the big job of moving your chain side-to-side from one chainring to the other. And while being utilized less and less on mountain bikes in favor of single chainring set-ups, front derailleurs remain an integral component on the majority of modern road, gravel, and cyclocross bikes that typically have two chainrings, though “triple” set-ups are also still in circulation.
The key part of front derailleurs is the cage in which the chain passes through. When properly adjusted, the chain only touches either side of the cage during the execution of a shift. Any chain rub is a sign of an improperly adjusted front derailleur. The cage is held securely in place by a movable arm, which typically has what’s known as a parallelogram mechanism that keeps the cage properly aligned with the chain as the front derailleur moves back and forth. Front derailleurs also have two adjustable limit screws that keep your chain from being thrown either inside or outside the chainrings, also known as dropping your chain.
Front derailleurs are connected to bar mounted shift levers via cables, or in the case of electronic drivetrains, wires or wireless technology. When the rider engages the front derailleur shift lever, typically located on the left side of the handlebars, it moves (or derails) the chain from one chainring to the next, providing an easier or harder gear.
When shopping for front derailleurs, you’ll need to know which brand, model, mounting type, and the number of gears your drivetrain has.
