Formed from the same DNA as its big siblings: DEORE RD-M6100 12-speed Rear Derailleur from Shimano

Molded from the same DNA as XTR, DEORE XT and SLX, the new M6100 series delivers Shimano’s proven 12-speed technologies at DEORE level.  The 12-speed DEORE rear derailleur enables precise and quick shifting within the 10-51T 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.
