This may be an absurd requirement, but my bike is in the shop for an extended period of time because of the parts shortage. I have a Fuji Feather that I use to commute, and I am looking for a smart trainer that I could use that on whenever the road bike is not available. I have a similar single-speed on another continent, so if I could travel with the trainer all the better.
But I have yet to find anything that can accommodate 110mm dropout spacing… The exception is the stac zero, but the fliiiight is out of stock and has been forever… Also, I have a stac zero and that travels fine, though it’s power meter broke on the first flight.
