The Shimano Deore RD-M6100-SGS is a long-cage rear derailleur for 1x12-speed mountain bike drivetrains. It handles cassettes from 10T up to 51T with a 41T total capacity, and it is made for a single chainring up front.
SHIMANO SHADOW RD+ is the built-in chain stabiliser, which Shimano says reduces chain drop, slap and noise. Larger 13T pulleys help with efficiency and chain management, and the low-profile shape helps the derailleur avoid damage from rocks.
