SHIMANO GRX Gravel Rear Derailleur RD-RX400 10-Speed

Shimano GRX RD-RX400 rear derailleur - MTB technology for Road 10-speed

The Shimano GRX RD-RX400 rear derailleur is designed for smooth, consistent rear derailleur shifting on rough terrain. Thanks to Shimano Shadow RD+ technology with on/off stabilizer, you don't have to worry about chain slaps or drops. RD-RX400 is compatible with all newer Shimano 10-speed STIs and with 10-speed cassettes up to 11-36.

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.

OT-RS900

For Dura-Ace, Ultegra, 105, GRX and other 11-speed or 12-speed road and gravel rear derailleurs, Shimano has developed the special OT-RS900 cable housing. It is less stiff than the conventional OT-SP41 housing and is therefore better suited to the tight curve where the cable is routed from the frame to the rear derailleur. Thanks to OT-RS900, problems with the barrel adjuster can be prevented and the rear wheel can be removed more easily. OT-RS900 is not intended for use on the shift/brake lever side.
