Hi all,
Well, I finally acquired an old Peugeot - I think '85. So I take it out of the box and it looks great; the color is better than I thought it would be. Then I look at the seattube collar - where's the bolt?! Where's the seatpost clamp?! How am I suppose to put a seatpost in this? It's just a stubby little curly seattube collar with no room for a binder. I know it's a 26.4 diameter. Anyone know how the seatpost clamps on? If the previous owner broke the clamp and hacked it off so it's unusable, i'm going to be pretty pissed :mad: .

And what's a pantagraph seatpost?

Thanks. I'm pretty new at this retro thang.

I can't help you with the binder question but a pantographed post is one that has a name on the post. Example might be Merckx. Cinelli might have made the post but it has Merckx pantographed on the post. I was pretty common in the 70's and 80's.

If it's bonded aluminum or carbon, it's a Vitus. Some Vitus frames had a set-screw that came in from the back of the seat cluster to hold the 25.0 mm seat post.

I think there were some French frames that used a seatpost that had an expander wedge like a stem, but I don't know who made them.

If you've got a digi-cam, post some pictures, it'll help a lot

My digital camera is being fixed at the moment. Here's my best 5 min sketch of what the seattube lug looks like.

An expander nut from the inside of the seattube?! Interesting, how would you adjust it?

Well, I guess I need an "expander" seatpost (you're right tube_ee). Anyone know where I can get one of these in a 24.6 diameter?

26.4 post and 501 tubes. Mid '80's Peugeot.

It doesn't have a clamp or binder. On the back of the seat tube few inches down from the top is a screw that tightens to hold the post in and loosens to release. I guess it tightens it internally, but it works really well.

If you don't see the screw you should at least see the hole, and can buy a new screw.

There is definitely no hole in the back of my seat-tube. I talked to another Peugeot owner and he told me about the expander post where the screw is on the the top of the post, under the seat. After adjusting the height of the post, only then can you install the seat. Do you have any pics of your Peugeot?

is a manually-operated engraving machine which transfers characters to the workpiece from a template at a given ratio (something like 6:1) to reduce error. Therfore logos will have to be engraved rather than merely etched, laser-etched, painted, or decaled in order to fit the definition.
Also: many times on castings, logos are cast in place and then cleaned-up and filled with paint-that's not pantographed. If your stem is not a forging but a casting, then it probably is of that type.
