At the tail end of my PX-10 teardown, I noticed there were no washers under the crank fixing bolts (Stronglight 93, if that makes a difference). There should have been, right? Thx...

I haven't checked the threads yet, but drilling holes in one of the dust caps to get it off (wow, it was on there!) I dinged up the bolt underneath. I imagine it will still do the job, but if the threads match one of my Sugino or Campy bolts, I might just substitute them. My experience with the Stronglight stuff so far (fixed cup wrench size, dust cap thread diameter) suggests the odds are good that the crank fixing bolt threads will be unique as well...
