Make sure they are lubed well, and do a movement test before installing cables. That is, ensure that when you pull the lever for the rear shifter up, the whole lever assembly for the front shifter moves as if it is sliding down the downtube. These can easily be reassembled 180 degrees wrong, in which case the auto trim will move the front derailleur in the wrong direction. It's a brilliant design, but can be finicky to set up. Don't use a late model Superbe Pro front derailleur with these, as the cages seem to be narrower and you'll wind up trimming your derailleur anyway.
