11 Speed Mountain Bike Rear Derailleurs

The rear derailleur is one of the most important parts on the bike and ensures precise, fast and smooth shifting. Shimano and Sram are the leaders in derailleur development. We have rear derailleurs for mountain or trekking bikes designed for 11 speed systems with single, double or triple chainrings. 11 speed rear derailleurs are compatible with 11 speed shifters, generally from the same manufacturer. The length of the derailleur cage determines its ability to handle different sized cassettes.
