The Shimano Alivio Rear Derailleur RD-M4000 was designed to help cyclists take on more difficult riding conditions thanks to a low profile and single tension construction. This derailleur helps minimize chain slap even in the most difficult and tough conditions while you ride. You’ll get a smoother ride that’s also nice and quiet. It’s ideal for recreational and mountain cyclists alike, making it a versatile choice for riders of all experience levels. A rear cable adjuster and tension spring give you easy installation and it is also direct mount compatible, so you install it quickly and use it on a number of different bike configurations.
