What is the seat post size for a Varsity and did it change over years? Also are there any alloy post versions available?

How old of a Varsity?

on the 60's-70's Electroforged ones its super skinny, under 25mm.

**edit**

a little googling says 13/16" -aka- 20.6mm

I can measure at home after work if nobody else can confirm this.

Thanks for the reply...
The bike in question is the '82 model I was given a week or so ago.
It had no post in it and I am doing a mild upgrade and want to find a ally post for it.

Try carbon. If you want to lighten the tank-like ride, get alloy wheels. It will make a difference in how your Varsity rides.

Already there! I fitted a set of Alloys and also a alloy stem and bar set. I've ordered a kit to convert to a 3 piece bb/crank but need the post to complete. Can you point me to one?

I have a Varsity from about 1980 or maybe 1982. Want me to measure the seatpost?

Please if you would. I swear Schwinn was worse than the French with their odd sizes

Not 100% sure, but if it is steel thatn it is a 13/16" size. Don't know if they make an alloy post in this size, since it is less than 25 mm and less than Peugeot 24mm size.

I measured it just now. Sorry it took so long. It came to 20.5 mm, which I suppose is close to 13/16". My caliper isn't the best.

Wald makes a steel one, Wald Cat#s 940, 945, 950, 955. These fit a standard seat clamp unlike the OEM seat posts. See p. 19 of their catalog... https://www.waldsports.com/files/WaldSports/Catalog.pdf . These are available from retailers like Niagara Cycle Works and Bikepartsusa but the images shown are wrong; look at the Wald catalog for the correct image. I don't know where to get an aluminum one.

Good luck!

Here you are. I'm not sure how much weight you'd save, compared with a steel seatpost, since it's so narrow, but you do have the option.

13/16" is 20.63750mm, so I guess 20.5mm is the same size. And I probably didn't measure accurately enough, but I'm sure you could use the Truvativ I cite above.

Oops, never mind. That's not 20.5mm at all!

It seems your only option is the Wald. Do you have a seatpost currently and are you looking to replace it? Or do you need one because your bike doesn't have one?

Sheldon's database sight states 21.15 for the varsity....old peugeots (the carbolite frames) had a aluminum post (mast type) @ 23.4.....could grind down? Good luck

Thanks for the reply's. 13/16" oh ok!
I don't have one for this bike so I need something..... I guess the Wald will be the one unless I do find a alloy to go with the rest of the deal

I'll send you one. I have a couple laying around The one I have is chrome and it's in good shape no rust. Its been cut down but its still 8 3/8" long should give you enough length I would say. PM me your address if you want it.

Thanks Stringbreaker!!!!! I've got a dozen various stems and none fit and the alloy I am searching for seems to be nonexistent....

Packed and ready to go. will send it out Tuesday

Thanks again! Another piece of the puzzle fit and squared...I'm getting closer!!

I don't think you can beat Peugeot for odd sized parts...

Possibly but I do have this Astra I've been told is a Motobecane built model that has a Swiss BB
but all the hardware is crazy sized as metric and standard size tools don't fit quite right...it's a adjustable wrench lover's wet dream

Scuze me, have you forgotten about Whitworth nuts and bolts?

Scuze me, have you forgotten about Whitworth nuts and bolts?

But isn't that a British system? The Astra is French... or did they just stop being homeys because they were made for the North American market?
I've heard that Astra's were a Canadian designated animal...

I just don't remember any odd-size parts unique to Peugeots.

Soonerbills: Post sent out this afternoon watch for it and let me know when you get it.

Thanks you a bunch!!!! I ordered a chrome clamp today... spent some time too at Fastenal for replacement stainless hardware for the brakes and such.... bit by bit!!
