<< I'm not so sure that the the seat post bolt on a Super Record post really had a 13mm head- every one I've had has been more like 1/2". The allen head bolt for the C-Record seat post part #7350162, will fit. This is not the same bolt as the the one on more common Chorus/Athena/Victory seat post, which had a coarser thread. Alternately, SRP used to make a Ti bolt, which you might be able to find. >>
David and All,
I think you are on to something! I just came back from the workshop where I measured seven (7) SR seat post (three are NIB) bolts. They ALL measured 12.8mm across the flats. I looked at my Norton International conversion chart and 12.8mm is closer to 1/2" (12.700mm) than it is to 13mm. That done, I picked out a nice 13mm craftsman box wrench as well as a 1/2" wrench and the 1/2" fits like the proverbial glove, while the 13mm is a bit sloppy!!!
I always thought the damn bolt was 13mm and never gave it a second thought until now!!
Keep it original!!!
