Ok, I've searched and searched on this, and found nada. I need to get the cassette off of one of these to replace a spoke. How the deuce do you do this? I've seen oblique references to some special tool, but nothing more than that. I'm willing to risk trashing the wheel if there's some way to do it with a drift pin and BFH or whatever.
BTW, it turns out that "FF" stands for "Friction Freewheel"
