|I'm cleaning my Campy rear derailluer, and after finally getting all the grease off them, I notice one says Lower and the other Upper. To me, they look the same, and unlike my XTR RD on my Mt Bike, one does not seem to have play.
Nonetheless, does it matter where each goes? And if the answer is yes, which is consider the lower (the one farthest from the derailluer body)?

|The upper pulley has to have some left/right play to aid in shifting. The upper pulley is closer to the cogs, so named because it's above the lower pulley.|| |
