Find your flow with the Shimano RD-M820 Saint rear derailleur by Shimano

The Shimano Saint 10-speed rear derailleur RD-M820 has a mode converter that can be used to switch between a maximum number of teeth on the largest sprocket of 28 teeth (DH mode) and 36 teeth (FR mode). The built-in Shadow+ stabiliser counteracts chain slap and chain drop. In this way, the Saint rear derailleur helps you to always find your flow, whether in downhill races, freeride adventures or in the bike park.

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.
