PRODUCT DETAILS

The Shimano RD-RX820 rear derailleur is compatible with 11-34t and 11-36t 12-speed cassettes, providing a wide gear range so you can spin a comfortable cadence no matter the terrain type.

The chain tensioner has an ON/OFF switch for outings on smooth surfaces.

  • Shimano Shadow RD+ offers less distraction, a quiet drive train, reduced chain slap and a solution for chain drop
