Hello Tandem Tom,

I have found that the Campagnolo headcup removal tool is handy and quick for knocking off the backside of headplate rivets. Alternately, a half-round bastard file can do the job fairly fast. You of course want to have the headcups out first. The plates can be refastened with a pop rivet tool. It is often necessary to file the backside or the finished rivet so as to clear the steerer.
