Thats the reason i just assume its the SC clutch engaging.
But i never really hear any noise accociated with it. Its more of a feel. Under such light load the extra drag on the crank from the SC is enough to actually feel like a slight hesitation for a split second.
I've noticed this as well, and ProjectMayhem is dead on about the symptoms (last paragraph pretty much sums it up). In my case, this symptom is separate from the fluttering that satellite is talking about (and I'm sure it's the same for him).
