The Shimano Deore RD-M6100-SGS Rear Derailleur delivers precise, stable, and silent shifting performance for 1x12-speed mountain bike drivetrains. Engineered with SHIMANO SHADOW RD+ technology, it offers a low-profile design that prevents damage from rocks and trail debris, while the integrated chain stabilizer minimizes chain slap, drops, and noise for a smoother, quieter ride.

The large 13T pulleys improve chain management and drivetrain efficiency, and reduced tension in low gears enhances drivetrain silence and durability. Built to handle the wide-range 10-51T cassette, the M6100 ensures consistent, reliable shifting performance across the entire gear range—perfect for modern MTB and trail riders seeking durability and control.
