The Shimano Alivio M3100 rear derailleur delivers a low profile design that lets you ride aggressively with fewer interruptions thanks to its Shadow design.

 

Shimano Shadow rear derailleurs are intended for more aggressive riding. Their super low profile design carries many benefits. Because of their low profile and single tension construction, Shadow derailleurs do not hit the chain stay in rough riding conditions. The result is smooth and silent performance.
