Shimano Zee clutch derailleur
The Shimano Zee M640 Shadow+ 10-Speed Rear derailleur features their unique Shadow RD+ technology, which is proven to reduce chain slap alongside drop and impact noise. It has a low profile that neatly tucks the short cage safely below the cassette cogs. Ideal for long recumbent chains as it reduces chain slap significantly.
