Wanted to see if there are others with Topolino before asking about them ...

I don't need info on them, I have a set. Have been riding Topolino C19 for over 1.5 years with no problems and enjoying the light responsive damping features of Topolino.

Yet, now 8000 miles later, I am starting to have mechanical problems with them. First, loose hub. Second, needed my hub body replaced. Third, hub not engaging after body replacement. Finally, a broken nipple. Talking with both Topolino Tech and my LBS to fix all problems. Don't know if this is the nature of the wheelset or simply the wheelset with use. ALL NEW TO ME!!!

So my questions:
1. How long are wheelsets suppose to mechanically last prior to service and problems.
2. Topolino users: Any mechanical problems -- what and when did they start happening?!!
