Classic & Vintage - super record seat post bolt

My SR seatpost bolt (~1980) is pretty flat, and hard to tighten properly. Is there an acceptable substitute or should I just deal with it? I would like to put in an easier bolt to work with, and save the o/g bolt for future usage if need be.

I know the first of the 90's era Record posts had an allen key version of this same bolt. I've had my eye out for a suitable replacement for my S-Record post too to upgrade as well, but haven't come across anything as of yet. Hopefully someone will have a suggestion.

I've ground the closed end of a 1/2" combination wrench down so that there is no taper around the inside edge to grip mine properly. I haven't investigated a replacement bolt. Is it an unusual thread? I'd expect it to be a typical M8 or something.

Cinelli provided a replacement, alloy, allen headed bolt with their saddle that was part of the Cinelli 'VIP' set. The rails of the saddle were alloy and had a wider cross section requiring a lslightly longer bolt.

Perhaps a replacement allen headed bolt would allow you to tighten the saddle clamp sufficiently. I have also had problems tightening the Campy bolt also.

OMAS probably produced an alloy or titanium replacement bolt as part of their bolt set upgrade for Campy Nuovo/Super groupsets.

This is where it starts, man. First you subsitute a non-Campagnolo bolt for your seatpost, figuring, "what harm can it do?" Next thing, you've got Shimano pulleys in your SR rear derailleur, and pretty soon, you're on here talking about how much better shifting the Superbe group is. Stop now, before the gravity of functionality pulls you down that slippery slope at the top of which sits Campagnolo, in all its pure aesthetic glory.

Well I went to the hardware store yesterday and bought a proper 13mm box end wrench, slightly longer than the crappy open end one I was using, and that worked pretty well. I guess my Dad was right, he told me long ago to use box ends when possible. I think I have the saddle position dialed in now so I shouldn't have to change it anytime soon. The bolt head was starting to show signs of wear from my previous efforts to tighten it, but if I leave it alone now it should be fine for future (box end) adjustments.

I'm sorry - I didn't realize it was already too late for you, if you weren't using a Campagnolo saddle wrench to begin with. ;)

I use a six point socket and my bolt is unmarked.

Anybody want to trade their 26.4 aluminum shaft, badged Simplex post in excellent condition for my 26.4 SR post in excellent condition with box?

Picchio Special's plea for ethnic purity aside, I find a hex socket head screw much easier to deal with, and I have all the proper tools. Find out what thread it is, and buy a stainless one in the right length from McMaster Carr. Save the old Campy bolt for the obsessive collector to whom you might sell the seatpost one day.
