A 7 speed should be able to fit on there if it is a newer Cyclone (126 OLD), I would think? If so, a Suntour 7 speed would work well. I am guessing they are:

Did any other generation of Cyclone have hubs?
However, is the rear derailleur an XC, XCD, XC Pro, XC-1? They all have their quirks, though shifting in friction mode, cannot really imagine an issue. On the long-cage XC, 38 chain wrap, so you are probably cutting it close if you went 14-32.
SunTour 7 13-26

SunTour Alpha 7 speed

I'm wondering if you could get it to index with the second one?
