Technology:

Shadow RD+
Shadow Plus rear derailleurs are just as low-profile as Shimano's Shadow rear derailleurs. In addition, a stabilizer with on/off switch is used to reduce chain slap and thus counteract chain drop. At the same time, this results in a quieter drive. Weight is also saved compared to other chain restraint devices.

Installed on a renewed 1999 Sintesi MTB converted from 3X8 to 1X12 speed works flawlessly and it’s perfect even for retrofits.

Too weak, it is the second one I broken in 6 months. Works well but it is not strong enough for its purpose, very small pieces of wood can broken it.
