Road Bike Rear Mech

The rear derailleur, often referred to as the rear mech, is one of the most important components on a road bike. Responsible for moving the chain across the cassette, it allows riders to adapt to changes in terrain and maintain an efficient cadence. A high-quality rear mech ensures smooth, accurate shifting, reduces drivetrain wear and gives you the confidence to ride harder, faster and longer. At Swinnerton Cycles, we offer a wide range of road bike rear mechs from leading brands, helping every rider achieve reliable performance whether training, racing or enjoying weekend rides.
