An even more difficult combo is old Zeus cranks with 16mm bolts. Because Zeus used these in combination with 22mm extractor thread on the arms, the fit is even tighter than Stronglight. You really need an old thin wall crank bolt tool, as most ratchet sockets are too thick. The old Stronglight extractor tools work well on Zeus bolts (but not arms). The Stronglight tool used to be sold in bike shops for a couple of dollars. They included the extractor, which had a 16mm head on the extactor bolt. The tool also included a 16mm thin walled socket and lever bar. The socket was used not only to turn the extractor, but also to remove the 16mm Stronglight crank bolts. Another of those odd but clever little French bits.
