Road Bike Derailleurs

Road bike derailleurs are essential components that manage the shifting of the chain across the bike's gears, ensuring smooth and precise gear changes. They come in two types: front derailleurs, which move the chain between chainrings, and rear derailleurs, which shift the chain across the cassette sprockets at the rear wheel. Explore the latest road bike derailleurs from brands such as Campagnolo, SRAM and Shimano here at Sigma Sports.
