Indoor bike trainers & thru axles

We get a lot of questions about if/how OPEN bikes can be used on an indoor trainer. And our answer was always as simple as it was unsatisfying: "We have no idea, we never ride indoors, we ride outside regardless of the weather."
But I understand that for some of you, this is important, so I asked our good friend Jeff Frehner, an OPEN rider and president of Powertap/Cyclops, for his expert opinion on the matter.
His top recommendation would be the Cyclops Hammer. This is a trainer where you remove the rear wheel, and it is compatible with thru-axles both 142 and 148mm wide (so for the U.P. and ONE+ respectively). This is how it looks, you can see the cassette body where you would install your cassette of choice, and then you install the bike with this trainer as the "rear wheel" (the setup shown is for QR frames but it works for thru-axle too):
