Does anyone know if Maillard Aris cogs would fit on a Regina freewheel? I'm trying to get a synchro system to work and I'm so close. Close enough where I am riding with the shifters using the indexing instead of friction. I'm thinking the Aris tooth profile would be a great thing to try. My hub is french thread and I already have the freewheel body. So I'm looking at just getting an Aris setup not worrying about threading to try it out.
