Oh, and with a hanger (if in fact you can mount a cyclone to a hanger - I don't know) the Cyclone might not have enough travel to reach your innermost cog. I've tried the Cyclone GT on a 7 speed cassette without luck. I even had trouble getting it to shift to the large cog on a 6 speed freewheel, and I think the problem can be attributed to an offset integral derailleur hanger. So, a hanger your type might offset it enough to cause problems.
