Don’t know about those specific wheels, but i’ve seen other Axis wheels on 10 speed Specializeds which had 11 speed compatible free-hubs.

Suppoedly, the newest Tiagra (4700) rear derailleur has the same leverage ratio as the Shimano 11 speed sets. If that’s so, and you want to upgrade to 11 speed on the cheap, you should be able to do it with only a cassette, chain, and right brifter.
