Rear Derailleur 105 11speed RD-5800-SS

Shimano launched a brand new version of one of the most popular road groupset worldwide, the 105. The new 105 (5800 series) adopts key features of the earlier introduced race proven groupsets Dura-Ace and Ultegra and brings it to the cycling enthusiasts for every day riding. The main new features are an 11-speed drivetrain that shifts more precise and lighter than ever, improved brake power and better control of the bike. 

The 5800 rear derailleur has a new spring mechanism and cable pitch, which provides robust adjustability. 

The short rear derailleur is not compatible to the 11-32 cassette!
