Not sure if you got an answer....I raced mine too with 46x15 gearing and had the same problem. Serviced my free-body and it cleared the problem. Free-bodies not meant to work so hard
I have posted about ethics.....and learned something in the process. Hubbers will sometimes sell to a more convenient person......in order to not have to pack and ship the parcel.....we have to live with that.
I also like Alfas but still won't drive one....... Have never owned anything but Shimano group-sets Love my Eurus wheels though.......they crap all over any Shimano wheels I have ever owned including my RS80's
