The Shimano Rear Derailleur 2x10s is designed for riders who want smooth, reliable shifting across a wide 10-speed cassette paired with a double chainring setup. Built with Shimano’s proven engineering, this rear mech delivers crisp, consistent gear changes whether you are climbing, cruising, or sprinting. Its robust construction is made to withstand everyday riding, while the refined spring tension and cage design help keep the chain stable and quiet, even over rough roads or light off-road terrain.
This 2x10-speed rear derailleur is a great choice for upgrading an older drivetrain or replacing a worn component on your road, gravel, trekking, or hybrid bike that uses a double chainring. It is compatible with Shimano 10-speed shifters of the same series type, making installation and setup straightforward for home mechanics and professional workshops alike. With a balance of durability, performance, and value, the Shimano Rear Derailleur 2x10s helps restore precise shifting so you can focus on the ride instead of your gears.
