Shimano ZEE M640 Shadow Plus Rear Derailleur

The Shimano ZEE M640 Direct Mount FR Shadow Plus Rear Derailleur can accomodate up to a 36 tooth cog while maintaining a low profile to reduce chain rattle and a reduced risk of dropping your chain over bumpy terrain. If you use this derailleur in combination with a road cassette the max cog you can run is a 28 tooth. This derailleur was designed to work with 10-speed drivetrains.
