Are you sure about the chain? I've NEVER had any problem running any Stronglight crank with PC-48/58/68 chains. These, I think, are/were sold a 6-7-8 speed chains, and are direct decendants of the SedisSport. I almost always use these chains with French bikes or Stronglight cranks, unless I have an older Sedis available. I don't know about modern 9-10 speed chains or narrow Japanese chains with Stronglight cranks.
