This is a traditionally-sprung rear derailleur designed to complement standard trigger or twist shifters. Shimano shifting technology keeps your drivetrain shifting nice and smooth.
Please Note: This is marked an OE Item because it lacks original packaging. The item has never been mounted.
- 9 Speed compatible (works just dandy with 7 or 8, or even Shimano Road 10 speed as well)
- Long (SGS) Cage for usage with triple cranks. (Will work with double or single ring drivetrains as well)
- Sturdy Alloy Construction
- Approximate weight claimed 275 grams
- Best matched with Shimano Rapidfire trigger shifters, SRAM Rocket or Attack (Shimano-compatible) twist or trigger shifters
- Will not work with SRAM ESP 1:1 shifters (SRAM x.0, x.9, x.7, etc). It will work with SRAM shifters specifically designed for use with Shimano derailleurs, such as their Attack or Rocket models)
Please Note: This is marked an OE Item because it lacks original packaging. The item has never been mounted.

Comments about Shimano LX M581 Rear Derailleur:
I installed this LX mountain derailleur on my gravel grinding/long distance recreational road bike with an 11-34 cassette, compact crank and down-tube shifters. It works great and it's silver rather than black or silver/black. It's good looking, dependable and inexpensive, what more can I ask?
