Shimano Deore RD-M5120 Rear Derailleur - Shadow RD+ | 10/11-speed | long (SGS) - black

Shimano Deore M6100, M5100 & M4100

After the mountain bike flagship XTR has already set benchmarks and Deore XT and SLX have followed suit, the Deore M6100 now rounds off Shimano's 12-speed lineup. It is complemented by the components of the M5100 and M4100 series which will equip 11- and 10-speed drivetrains at the same high level.

Regarding the price, the current Shimano Deore groups are positioned in the entry-level range, but are not prepared to compromise in terms of performance, quality and reliability. Almost everything that the high end groups XTR, XT and SLX have to offer in terms of technology, innovation, performance and range of functions, you will find in the Deore components, too.

Shimano Deore RD-M5120-SGS Shadow RD+ rear derailleur

Thanks to its Shadow RD+ design, the Shimano Deore RD-M5120-SGS rear derailleur delivers consistent MTB shifting performance over rough terrain. The low profile design avoids damage from rocks whiles Shimano's chain stabilizing technology reduces chain drop, achieving a quiet drivetrain in all gear positions at the same time. 

The Top Normal rear derailleur is suitable for 1x10-speed (max. 11-46 teeth) as well as 2x11- and 2x10-speed (max. 11-42 teeth) drivetrains. The guide and tension pulley of the long SGS cage feature 11 teeth each.

Shadow RD+

Quiet drivetrain, less distraction. The Shadow RD+ system is lighter and more efficient than roller type chain devices. A rear derailleur stabilizer reduces chain slap and is a simple solution to prevent chain drop as well.
