I got one answer from Shimano via Facebook (July 2017), but this is NOT CORRECT.
Do you know if the Shimano Alfine 11 has automatic shiftin possibilities with the STEPS systems?
I to ask in many local shops, but they didn't know, I asked bike builders, but they didn't know. They only have bikes with Alfine 8, for which the automatic shifting works. I've looked into forums, checked your Shimano websites back and forth, but I didn't find any information.
I would be considering to buy a new bike with Steps and Alfine 11, if it has automatic shifting. If not, I would stay with Alfine 8. However, in our hilly city, Brussels, the Alfine 8 often feels not enough in range.
Thank you and kind regards,"
"Thanks for contacting. Shimano Alfine 11 speed hub is available with Shimano STEPS, but Alfine 8 isn't. Unfortunately automatic shifting is also not available yet in combination with STEPS. We can't guarantee this will be in the near future.
