Is the Rollapaluza rule that they have to use 125mm cranks, or that nobody can use cranks shorter than 125mm? The latter sounds like a more sensible rule, there's no advantage in restricted-gear events to using long cranks, so there's no reason to prohibit them, whereas short cranks favour the strong, which is what they are trying to avoid by restricting the gear ratio in the first place.
