Classic & Vintage - G S seat post

I have an italian seat post with the initials G S (in cursive script) the word brev. and a 27.2 o diameter.

any clue on this one? I came off a late 70's AD olympian.

Campagnolo Nuovo Gran Sport. Mid '70s through early '80s.

Not sure on this, maybe Campy GS? Does it say made in Italy anywhere??

wait, sorry It says G L (I had G S on the brain I guess)

Brev. is italian from regi. trade mark of something similar.

Well now, GL, that is a whole nuther story! Some potentials would be Galli, Gipiemme, etc. Not sure on that one at all! Sorry!

I just sold that exact post on ebay a couple months back. Mine came on a Puch Marco Polo. It was marked 27.2 and would slip down on its own. I measured it and it was closer to 27.0. I couldn't find the auction to show you the photos but I believe I had exactly the same thing the the cursive script. I advertised it as Italian, maybe Selcof standard issue.

thnaks, let me know if you find a picture or get in info. I am really curious!

I had one of these, and they are not Campy Gran Sport. I wish I could remember what the initials stand for, I have a vague recollection that it might be French, and not Italian, but...could be wrong..."brev." can be the French abbreviation OR the Italian abbreviation for "patented", so that doesn't help in this case.

I won't be able to be sure without a picture, but that sounds a lot like a San Marco GS Lux (according to the catalog) I had on a mid-80s Gitane. It stumped me 'till I found some Gitane catalogs but it was pretty nicely made.

It is GL no GS sorry for the confusion.

Actually...seems we all had it wrong, according to some expert sharpshooters at the CR list, it's actually not an "S" or an "L", but a "P"...and now that rings a bell cause I KNEW the letterform was a bit weird and could pass for more than one letter.
Seems it's an early Gipiemme, and maybe before they added the "M" initial...so it's Italian, and regarded as a good, cheap (cause they sell cheap on eBay, so says one guy) substitute for a Campy seat post.
Now I can take a nap.

Actually, I believe it is GR: Gian Robert. I have one as well.

That's a quote from the CR archives, and this poor quality pic is what matches the post that I had back in the past, I'm going with Dave on this one: Gipiemme (plus he clears up another misconception of mine, I thought GPM were three individuals, guess I was wrong...again)

that is the correct script! thanks guys. My seat post is smooth not fluted though. It bike has gipiemme drops so that makes sense, and what my semi-educated guess would have been.

thanks

These seatposts were sold in the UK as San Marco seatposts - I have had a small batch of them from a wholesaler and they come in a printed polybag with the San Marco name. They are a very nice 1970s period seatpost albeit a little short.

This is good news for me....(being short) I have one VERY sunk and stuck in a frame. May any of you know how far the tube starts down from the solid attachment clamp? May have to cut this flush and wonderng what I'm dealing with. I've destroyed a seat-rails and clamp so far. :twitchy: Any ifo appreciated. Other than this post, I haven't found a picture of a GS anywhere (save for one on a bike in a catalog)

They are about 190mm from the rails to the end... I think this will be a melt-out job as the walls are quite thick...

Thank you

is true, luckily I could get my seatpost GP

Thank you

DANG Luis!!!!!!! I'm in trouble.......tried soaks in various chems/twisting.-ruined seat and rails-drilled through the clamp to use a rod-hacked it off (had to be flush as it was jammed waaaay down) And now I'm at this point (pics) Have 2 sections sawed...guess I have a way to go. Very thick tube. Thanks for the pictorial-inspirational.

I spend the same. I had to find a turner and carefully cut with a hole of 26.8 mm the seatpost piece needed to put another new saddle stem. lucky!

I had to use a milling machine

That would be handy! As it is-one gram at a time....(with a round file)

I don't even know what language this is (Spanish? Catalan?) but the pictures tell the story. Great restoration job on a great old bike. Very impressive.

I don't understand this. just why does it make sense that the seatpost might be Gipiemme simply because the dropouts are Gipiemme?

Sorry to drag this thread back from the dead, but a G.P. marked seatpost is for sale here (http://www.bikeforums.net/showthread.php/714168-Calipers-bar-ends-derailleurs-post-Suntour-Weinmann-Shimano-Campy) on BF which can positively be identified as a 3TTT Gran Prix post. It is only marked with the script G.P., which the seller astutely correlated to the model name.

So perhaps not Gipiemme after all.

I have had quite a number of NOS seatposts of this type and they come in San Marco poly bags. They are not like either of the two 3TTT seatpost designs...

Like the one pictured below? This was equipped on a mid 70's Austro Daimler Inter10. It's got the same G.P. script logo.

I'm still not convinced that Dave Anderson had it wrong when he said this is a GP brand before it became GPM (otherwise known as Gipiemme)...San Marco does not mean Selle San Marco, and if Hilary says it is nothing like the two 3TTT post designs he's seen, I have to give that observation a lot of weight....he's seen much more of everything concerning bicycles than anyone else here.

Fair enough. I suppose some Italians have a penchant for stamping their seat pins with a G.P. and nothing else!

I agree the first letter is a G, but I do not believe the second letter is a P. I also don't think it's an L. I'll believe S, but am willing to listen to other opinions.

Well, I certainly won't question your credentials. The mystery deepens.

Thanks for that! I must admit, though, alphabetic scripts are not my forte.

Let's say it's an "S". I have seen Gipiemme BB cups marked "Gipiemme Special" and "Gipiemme Sprint", but I don't necessarily think either is what the G.S. represents.

And 'Gran Sport' is a fairly ubiquitous moniker.

I've seen one of these posts somewhere on a local bike before. Hmmm...

I grant that the second cursive letter is difficult to identify, it doesn't look like how I would write any of the possibilities: P, T, S or L, but then that "G" isn't something my third-grade teacher would have given a passing grade to, either.
I'm still in the "Giovanni Papillardo de Milano" camp, until somebody can verify that some other company made the "San Marco" posts.
Just for more comparison, here's what one of the vintage 3TTT posts looked like (no family relation to any of the "G. P." posts I've seen)190301

I have one of those posts; it's from the company that later became "Gipiemme" (G.P.M.)

Hi
im a graphic designer, so I can say that it is a "S" the letter "P" have a different shape in calligraphic style.
And definitely it a seatpost by the italian brand "GS"
see here:

best

^I have never heard of that brand before, but the photos definitely settle the matter. Case closed!

me too
but on the box there is written "Produzioni San Marco" so GS it is a little sub brand of San Marco,
as someone wrote before.

Awesome. Put this one to bed. No relation to Gipiemme.

Put this one to bed.

I refuse. :P The post I had looks nothing like the posts in manmatova's link. I'm sticking with 3TTT for mine. The real question is, what's the relationship between all these various companies?

I refuse. :P Oh, be that way, makes no difference to the rest of us.


The post I had looks nothing like the posts in manmatova's link.I disagree. The finish is different, but the shape of the clamp parts, and the round groove in front of the clamp, all resemble the ones in the Italian ebay photos. All that's missing is that strange raised band. Anyway, the ebay photos closely resemble Jan's photos that you linked previously:

Earlier design that was copied by San Marco. Or San Marco was associated with 3TTT which was associated with GPM. Not necessarily in that order.

You're losing me. Are you talking about this post?

If so, it is stamped with the same cursive GS as Jan's post, and the ones on ebay. The ones on ebay come with packaging that proudly displays a block letter GS. I believe the equation GS = GS is pretty well proven. The packaging also suggests a connection to San Marco. So far no one has shown any post stamped GP, or demonstrated any connection between GS and 3TTT or GPM, other than the misreading of GS as GP, which we have now laid to rest.
