Precise, lightning-fast shifts across an 11-speed cassette, whatever the conditions, with just a button click. The Shimano Di2 9070 rear derailleur is now lighter and more compact, with E-tube connection to simplify installation. The derailleur has a built in mechanism that will allow the body to move inward under impact to reduce the potential for damage in the case of a crash.
