iPhone. But, as mentioned, not "controlling" it in any sense because I'm not adjusting resistance during rides. I do a spindown after each ride (or every other), but even so what's odd is it happens part way through the ride.
I'll try to make more mental notes of what else may be happening (data page changes, certain point in ride, etc.)
