Road Bike Derailleurs for Sale, Shimano, Campagnolo, Sram
A derailleur is an integral part of a road bike, containing sprockets that allow the rider to have varying gears that can be changed based on speed and terrain. On a bicycle the derailleur is the system that connects the chain and gears to a lever on the handlebars. When the rider moves the lever forward or backward, the chain is loosened and allowed to move onto a different gear.
The derailleur has both a front and rear component, each with its own job. The front derailleur moves the chain from side to side, helping to loosen the chain for a short time allowing the rear derailleur to move the chain onto a different sprocket. A derailleur is somewhat like an automobile transmission, allowing the rider to change gears from a lower or higher number based on the terrain and speed of the rider.
