Ah. The old, weird 13mm hex fixing bolt. What was Campy thinking, anyway? Go ahead and change the bolt to a quality 6mm hex of similar specs, as Brian suggests. Make sure there's a washer under the bolt head. I've done it numerous times, and it's even sort of period correct, since it was a fairly common "upgrade" at the time.

>>>Ann,

There is a 6mm allen bolt version of that seat post; the generation just after the 13mm hex version that you have. I've never tried it, but I suspect the parts are interchangable. I also seem to remember some aftermarket alloy seat bolts, but I'm not sure that is a real good place for such a bolt under the circumstances. I also think a properly threaded and proper length regular allen bolt would work; I would put two washers under the head of the allen bolt.
