Shimano Dura-Ace R9150 front and rear Di2 derailleurs with Ceramic Speed oversize pulley wheel system. Overall light use and bearings still in great condition and spin very free. Also comes with original cage which has never been used. Front derailleur in great condition with some slight chain rub evident. Rear derailleur also in great condition with exception of scratch on under side as detailed in second photo.
To buy new this would be over $1500. Priced to sell as a pair at $650
but will consider splitting for the right offer!
Happy to ship within US at buyers expense.
