Precise, lightning-fast switching operations on the entire spectrum of a 11-speed cassette - and this in every situation and literally at the touch of a button: the RD-9070 rear derailleur is more compact and lighter than its predecessor and has the E-tube connectors for an extremely simple installation. For the hopefully not occurring crash or other affecting forces, the RD-9070 is like the RD-7970 equipped with a crash mechanism, which disconnects the motor to avoid damage.
