I attached the rally cage on a Neuvo record RD that I had. It goes through the gears well. I had to add some chain. Of course I still need to find the 7 speed freewheel with 32 max cog. I seem to only find 28 max unless I go to 8 or 9 speed which will not work on my spacing. I do find a 34 and am wondering if anyone has tried a 34 with the Rally cage? I find reference to 32 being max.
