Shimano Deore M6100 Rear Derailleur

The all-new Shimano Deore M6100 rear derailleur brings Deore-level durability and refined shifting for modern 1x12 mountain bike drivetrains. Engineered with Shimano’s Shadow RD+ low-profile geometry and an improved chain stabilizer, the M6100 reduces chain tension in low gears and manages chain movement across rough terrain. Larger 13T pulleys improve drivetrain efficiency and reduce wear, while compatibility with Shimano 12-speed cassettes gives riders the range they need for steep climbs and fast descents. Built for trail reliability, the M6100 balances quiet operation, precise indexing, and serviceability so you can ride harder and maintain less.
