Shimano Dura-Ace 9070 Di2 Rear Derailleur

The new Shimano Dura-Ace 9070 Di2 Rear Derailleur brings fast, precise shifting to the 11-speed party. Whether you're cruising your weekend long ride or sprinting up the side of a mountain, the 9070 Di2 Rear Derailleur will shift no matter the conditions. Lighter and smaller than the 7970 version, the new size is so much more compact that you could mistake it for a mechanical derailleur. E-tube connection simplifies installation, but this new version is 11-speed only, so don't try to pair it with a 10-speed cassette and spacer. You've been warned. Features: 11-speed design Automatic crash protection Maximum sprocket 28T Compact, lightweight body Discounted at ONLY: US$ 549.99
