What does Ron Shaver does on the time mark 1:24? It looks like a 540 jump of some sort, I haven't seen such move on an ISU event AFAIR. Ò;ô

It's a single axel with a tucked leg position.

You don't see it because it's worth just as many points as any other old single axel (except with maybe some extra GOE).
