Please Help Identify this Seatpost
Hi all, I am in the midst of renovating a 1970's Atala. I am trying to identify this seatpost and also if it would be compatible with a newer style saddle. I am looking at the modern San Marco or Selle type seats. The seat post has no markings at all in order for me to ID the manufacturer. I am just curious what it may be.


Here's the Atala in progress (it's glare at the headtube not a paint smudge lol). The decals are paper printouts trying to determine the best look and placement.

Thanks

That bike looks nice.
It's hard to say what model that seat post might be. Back in the 70's a post like that with separate clamp were pretty common even on non-bottom-priced bikes. I have a Motobecane Le Champion for restoration with a post and clamp like that. You could replace the seat post if you wanted to but it won't save a lot of weight. You'd have to measure the diameter carefully with calipers and find the exact match, of course. FWIW, my Raleigh (Carlton) Gran Sport still has its original post and clamp, though IIRC the post is alloy, not steel.
Saddle rails are pretty much all the same distance apart so compatibility should not be an issue.

That seatpost should work with the vast majority of saddles. It is a pretty basic one, as newer saddles are lower profile, just make sure you have enough seatpost inserted into the frame, I like 75 mm at least. The clamp won't look especially attractive, but it should function.

I have about three of those type with only one identifiable as a Brooks. None of the others are marked. They are a bit heavy, being made of steel. I disagree with [MENTION=190941]jimmuller[/MENTION] in the weight comment if you consider an American Classic post as a replacement. The Le Champion he references includes a Brooks Pro, which weighs at least a pound, making the clamp a small weight contributor. Plus, the post on the Le Champ is AL unlike many others that are steel.
the post diameter will vary depending on who provided the post, though there are more of some than others. I suspect Brooks set the standard and the deviations were to drive purchase of other clamps and saddles at lower cost.

As for the Brooks Pro and the Le Champion, it's the only Brooks I have ever lifted and yes it weighs a ton. But then, the saddle weight has nothing to do directly with the seat post weight. I have not started on that bike yet but I am I quite undecided about what to do with the saddle. I have all the original parts and even the shop invoice so I'd like to keep it complete. That means keeping it heavier than it might be.

[MENTION=190941]jimmuller[/MENTION] - IIRC that bike should weight close to 22-23 lbs complete. Mine did with clinchers and is a 24" frame.

Since on topic of seats, can anyone help identify the model of this one? I know it's a San Marco but unsure of the specific model (ie. Concur).
I am unsure if it's worth fixing it up or replacing with a modern saddle.
