Shimano Deore RD-M5100 SGS Long Rear Derailleur

The Shimano Deore RD-M5100 SGS is a long-cage rear derailleur built for 1x mountain bike drivetrains, keeping shifting consistent over rough and technical terrain. A low-profile body sits tucked away from rocks and trail obstacles, reducing the risk of impact damage during a ride.

Chain stabilizing technology cuts down on chain slap and drops across the gear range, keeping the drivetrain quieter on rough trails. The derailleur also reduces tension on the chain in low gears for smoother pedaling, and a 13-tooth pulley wheel keeps chain tracking consistent through the cassette range.
