Oooh, 16 mm in a Campagnolo (or Zeus) crank can be a BIG problem.

Stronglight used a larger dustcap/extractor thread when they were using 16 mm bolt heads.

Zeus was the worst of both, 16 mm bolt head (copied from Stronglight) in a 22 mm dustcap/extractor thread (copied from Campagnolo.)

Zeus made a special super-thin-wall 16 mm "peanut butter" wrench for that, but as far as I know there's nothing else that works.

There's a guy in our club who's a big Zeus fan for some bizarre reason, and he was doing OK until somebody pilfered his wedge bag with his irreplaceable Zeus peanut butter wrench and now he's SOL.

Fortunately, he's also a fanatic about Phil Wood bottom brackets, so he has no real need to remove the cranks...
