LOWER RISK OF CHAIN DROPS

To be used with a semi-synchronized or synchronized shifting program ( SHIMANO SYNCHRONIZED SHIFT ), this derailleur has been developed to spread the chainline slightly while still giving you eminently efficient shifting performance. In addition, the system's communication with the rear derailleur and automatic alignment with the position of the chain on the cassette help to minimize the risk of chain skipping.
