Now with 11-speed compatibility and technology borrowed from Ultegra and Dura-Ace, the Shimano 105 RD-5800-SS Rear Derailleur has a new spring mechanism and cable pitch that provides "robust adjustability" for perfect alignment. Shifting action feels light and nearly effortless, even under heavy loads. Wide outer link design offers super-stiff, smooth and precise gear changes while the short cage design is compatible with 28T rear cogs.
