Overview
Rear Derailleur Shimano Deore RD-M5100 SGS 11-speed
The Shimano Deore RD-M5100 SGS is a durable and reliable 1x11-speed MTB rear derailleur featuring the SHIMANO SHADOW RD+ design for consistent and precise shifting performance, even on demanding terrain. Its low-profile construction protects the mechanism from rocks and trail obstacles.
The integrated chain stabilisation system reduces chain drop, chain slap and noise, ensuring a quieter ride in every gear position. Reduced derailleur and chain tension in lower gears improves control and maintains smooth operation when using large sprockets.
Compatible with 11-speed 11–51T cassettes, the RD-M5100-SGS supports a maximum sprocket size of 51T. The enlarged 13T pulleys reduce friction and enhance drivetrain longevity, making it an excellent choice for modern 1x11 MTB drivetrains.
