Product details
The Shimano Deore XT RD-M786-SGS Shadow+ rear derailleur is engineered for 10‑speed Dyna‑Sys MTB systems. It uses a long (SGS) cage that accommodates up to 36‑tooth rear sprockets and a total capacity of 43 teeth, making it suitable for a wide range of gear combinations. Constructed from aluminium, the derailleur weighs 258 g and features a low‑profile design that avoids contact with chain stays, protecting it in narrow passages. An integrated switch lets the rider select a higher spring tension to dampen cage movement, reducing chain bounce and noise, or a lower tension to ease rear‑wheel removal. The Shadow+ technology provides stable, silent operation across varied terrain, while compatibility is limited to Shimano Deore XT 10‑speed components.
