The springs in the current issue Campy Ergopower levers do take a set and lose their OOMPH if left stored in a "low" gear position for a long time. I always return by bikes to the hook with the gears in the position of lowest spring tension (altho with triple rings I leave the chain on the middle ring).

just my 0.0002.
