In my experience, I've found that you can clamp a track axle into most trainers - but the axle protruding from the nuts on most hubs can sometimes be a problem. If this is the case, you can simply thread on another set of track nuts. Also, the clamping surface on the trainer will round off the edges of the nuts, which is another good reason to use an extra set.
