    You’re welcome MrLeffe. One last item. Go here and download the free Shimano e-Tube Project.  http://e-tubeproject.shimano.com/  It’s what your LBS uses to update Di2 software, configure its operational functionality and to troubleshoot/diagnose Di2 issues. It’s very easy to use if you wish to make changes later on to shifting speed, L/R paddle funtionality, or to just perform a system health check.

    Sorry, missed your second

    Sorry, missed your second part about the chain. Shimano 10 and 11 speed chains have the same internal widths but not the same overall external widths. Yes, you can use a 10 speed chain on an 11 speed drivechain but there will be the occaasional/frequent chain rub noise. Chains are inexpensive so why not buy buy new to go along with your new drivetrain? You wouldn’t buy a new car motor/engine and use old oil would you?

    You can use your chainset no probs. Best to stick to the right speed chainset but I swapped to the 6800 crank running 10 speed 6700 and it’s absolutely no problem.
