Reliable and durable 10-speed MTB rear derailleur with a low-profile design

Deliver precise, fast, and stable shifting performance on the trail with the Shimano Deore RD-M593 rear derailleur. Engineered for 10-speed drivetrains, this component incorporates Shimano’s proven Shadow RD design, featuring an ultra-low-profile architecture that minimizes the risk of snagging on trail debris, rocks, and branches.

The M593 model is a Top-Normal derailleur designed for direct mounting to standard derailleur hangers. It features an upgraded, stronger return spring on the cage to keep the chain taut, drastically reducing chain slap and drivechain bounce on rough terrain. Its long cage (SGS specification) ensures broad chain capacity for wide-range cassette setups.
