Like an old book, a couple of pieces of wood, or whatever stays put. Pretty much anything works.
Cool, thanks! I'll probably start out with something home-made, then, until I can find a riser for cheap-ish. I wasn't sure if they were for height, or stability (since the ones I've seen seem to cradle the front wheel). Crossing my fingers I can make it work! I haven't the first clue exactly what it's supposed to clamp onto in back... there doesn't seem to be much sticking out. I might have to post a picture and ask here if I try it and get stuck.
I saw one video that recommended getting a cheap axle to use with a trainer so you don't wreck your "real" one? Should I do that? It sounds annoying to constantly be switching the axle in and out every time between indoor and outdoor riding... I haven't many bike-mechanic skills (at least, not yet...?) and it sounds intimidating to me, not like something I'd do in a quick five minutes.
