Ian WinterburnI bought this derailleur for a Di2 upgrade to my standard Ultegra groupset. It's brilliant, works effectively and efficiently, a great price and fantastic service from Merlin
Mr St-DenisVery accurate and smooth shifting, Easy to adjust and very reliable shifting, surprisingly light considering the extra electronic.
Eric JacksonThis is the medium cage Di2 derailleur which I needed for an 11-32T cassette. I replaced a DuraAce Di2 short cage. It really shifts fine, as good as the DuraAce in fact. But I did notice that the pulley wheels seemed to show wear more quickly - maybe not wear, but I think they are made of a different material than the DuraAce - no big deal though. Was instantly recognized in Etube and the firmware was up to date as well. Also, you can feel the weight difference. I would consider this a great purchase.
