ShimanoGRX RD-RX810 11-Speed Rear Derailleur(Return to Product Page)

My gravel bike came stock with a Shimano 105 rear mech, which shifted flawlessly. I was getting a lot of chain slap on bumpy gravel roads and descents. This took care of 95% of it. I will occasional see chain lube marks from the chain on the chain stay but that is only after hitting significant hard bumps.

This shifter is noticeably quieter! It also tucks under the accelerated cassette to move it out of danger. Haven't used the clutch yet since we are mostly on limestone trails but it's there if I need it!
