Compatible with up to 51T cogs, it features Shadow RD+ technology for stable, quiet shifting and a low-profile design to resist trail damage. Ideal for riders seeking reliable, precise gear changes on steep and technical terrain. ## Description Shimano has long been known for producing components at a great value that won’t compromise performance, quality, and reliability. This time, the RD-M1500 Rear Derailleur complements Shimano’s Deore mountain biking series by bringing consistent shifting performance for riding fast and steep trails. Improved stability and predicable control mean you will be able to push yourself further on your ride, climb steeper trails and zoom down descents. This rear derailleur delivers a low profile design to avoid damage on your ride from rough terrain. Chain stabilizing technology reduces chain drop which makes for a quiet drivetrain in all gear positions. The M5100 rear derailleur holds that same high level of 11-speed drivetrain as the M6100, and this derailleur utilizes Shadow RD+ technology to improve performance and consistent shifting.
