My search for Park Tool Cyclone brought up this old post. I just bought it because I didn't much care for the other chain scrubber I had. Now I'm not a rocket scientist but I am a step or two above an amoeba...still I can't get this thing to work properly. I put it on the lower part of the chain, which is level, pedal backwards and the darn thing keeps making my chain pop off. I'm in the smallest cog in the back and the middle on the front (I have a triple). What am I doing wrong?
