I am not certain the rear drops at only 100mm seemed more like 115-120 as I recall. I put a 126mm hub in there with a 6 speed suntour freewheel. I just squeezed it in. It fit fine with no problems. Previous to this wheel it has the original coaster brake wheel (a strumey archer). The front drops are around 100mm maybe that's what you're thinkin?
