Product Description
The Shimano Altus RD-M310 rear derailleur is a dependable replacement derailleur for compatible 7-speed and 8-speed mountain and hybrid drivetrains. Its Wide Link body design improves rigidity for more precise shifting, while Shimano’s SMART CAGE pulley plate helps provide better ground clearance.
Oversized 13-tooth guide and 15-tooth tensioner pulleys help reduce noise and wear, making this derailleur a practical option for everyday riding and drivetrain refreshes. The long cage design supports a wide range of gearing combinations and works with Shimano HG 6/7/8-speed chains.
This derailleur is in take-off condition and may show light handling marks, small scuffs, or minor signs of installation/removal. Any wear present is expected to be cosmetic only unless otherwise noted.
