The Shimano DEORE RD-M5100 1x11-speed rear derailleur for 11-51 cassette features an elegant yet aggressive angled design. The derailleurs feature bigger 13-tooth pulleys and include Shimano’s proven Shadow RD+ low profile technology.
Formed from the same DNA as its big siblings: DEORE RD-M5100 11-speed Rear Derailleur from Shimano
The 11-speed DEORE rear derailleur enables precise and quick shifting within the 11-51T range. 13-tooth pulley wheels and SHIMANO SHADOW RD+ technology reduces chain chatter and gives you improved chain retention thanks to a stiffer derailleur arm and higher chain tension.
