Reply To: Shimano 2013, Part 2, 9070 Di2 Dura-Ace

I have a number of 10 speed bikes Road bike, winter bike , TT bike. I regularly swap wheels about for racing, training etc. I would like to upgrade to Di2 but the 11 speed thing bugs me. Can I programme this from 11 speed to 10 speed? I would buy the original DI2 but I’m concerned they will phase it out and the new cabling seems a step in the right direction.
