With the GRX RD-RX812 rear derailleur by Shimano you can shift reliably off-road


With the Shimano GRX RD-RX812 rear derailleur you can shift smoothly and quietly on rough terrain. An adjustable chain stabilizer and the Shimano Shadow RD+ technology counteract chain slapping and dropping. Use this rear derailleur when riding an 11-40 or 11-42 cassette.

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.

Schaltet bei mit (illegalerweise) mit längeren Kettenleitblechen für mehr Kapazität und funktioniert trotzdem gut.
Der Dämpfer verschlechtert das schalten leicht, ich weiß nicht ob das so üblich ist bei solchen Schaltwerken

Schnelle Schaltvorgänge, klasse Bandbreite. Gute Kombination aus beiden Welten.

Hochwertig, leicht einzustellen, kompatibel auch zu 105- oder -Ultegra-STIs, präzise Schaltvorgänge. RD-RX812 funktioniert auch mit Kassetten mit 11-46 Zähnen (bei 1x11, bei 2x11 muss der Schaltkäfig verlängert/ausgetauscht werden).
