Good to know about the connectivity, the Specialized dealer said it did not connect, but he was not very knowledgeable about the bike. I ride mostly with the bike off and only use it occasionally, might explain our different impressions.
I have a Gain and I have been test riding both the Domane + HP and the Creo. If you want longer range and a wide power band the Domane is best. When I was riding it I was pretty sure that I would always use power because of how much it weighs. Both the Orbea and Specialized both ride very well...
