Shimano Dura Ace RD 9000 Rear Derailleur. It's rugged, good looking and most importantly, probably the best performing rear derailleur Shimano has ever created. The 11 speed Dura Ace rear derailleur features a lighter, more compact design than previous iterations and is paired with low friction polymer coated cables to deliver precise shifts with a remarkably balanced effort across the gear range.
