Shimano Saint RD-M820-SS Shadow RD+ Rear Derailleur 10-speed - black

The Shimano Saint RD-M820-SS Shadow Plus rear derailleur features a short cage, 10-speed compatibility, and a cassette range of 11‑36T. Weighing 280 g, it includes a silent bump stopper, integrated skid plate, and a spring‑tension switch for reduced chain bounce on aggressive MTB riding.

The Shimano Saint RD-M820-SS Shadow Plus rear derailleur is designed for mountain bikes requiring reliable 10‑speed shifting across a wide 11‑36 tooth cassette. Its short (SS) cage accommodates up to a 28‑tooth largest sprocket, delivering a 25‑tooth capacity. Weighing 280 g, the unit incorporates Shadow Plus chain‑control technology with a silent bump stopper that dampens cage movement, minimizing chain bounce and noise. An integrated skid plate protects the mechanism from impacts, while a dedicated switch allows riders to increase spring tension for a more stable chain line or relax it for easier wheel removal. The low‑profile construction keeps the derailleur clear of chain stays, enhancing durability in narrow or technical terrain. All components are manufactured by Shimano, ensuring compatibility with Shimano drivetrain systems.
