Alright folks my soon to be bike frame. I was looking through the online catalogs trying to find out what year/type this bike is. Anyone have a clue? It would help when it comes to getting a headset and "track bb" and fork to fit. I know it can be hard to find parts for French bikes so any help will be much appreciated. I guessing its not the Reynolds 531 "10" series, but it is a super light frame. Maybe its a cheaper baby boom bike? I love the head-badge but the paint needs to be stripped off. Will my english bb, headset fit this bike? thanks....... $20 bucks a good price for a beater frame?

Uo-8

20.00 is not bad considering where you are located. If you really want a old Peugeot its not bad, but it would have better with a fork.

Thank you very much

I think it's the fork that gives these the nice riding quality, anyhow.

The headset threading will depend on the fork that you choose. The bottom bracket will be French. Velo Orange makes one that many people like, and it's affordable.

Im getting the feeling that this might get more expensive than I first thought.

Oh, yeah.

Definitely.

My early 70's UO8 is reynolds 531. If you do end up stripping all the paint like I did, mine was labeled "Reynolds 531" on the top tube right before it get to the lug attaching to the head tube.

Mine also has same headbadge and decals were pretty close. Mine has a Stronglight crank, which is a pain. I checked five LBS and none had the crank tool to remove a Stronglight as they use a 23.35mm puller and the "universal" tools don't work for it. If yours is a Stronglight there is a tool that you can buy online but its pretty pricey for such a simple job.

I love mine, but it was pretty frustrating dealing with vintage french stuff and mine was complete when I got it. I can't imagine your future headaches, haha. Enjoy it.

Please post a picture of your Reynolds 531 UO-8!

Tha plastic head badge such as the one on your bike was first used on UO8's in 1975 and the shift levers migrated from the downtube to the handlebar stem in 1977. Based on your photo, your UO8 is either a 1975 or 1976 model year. Note also that your bike has cottered cranks so you will not need a Strongligh crank removing tool; a cotter press is what you should have.

"Higher-end Peugeot models from this era, notably the popular PX-10, were made with Reynolds 531 tubing and are labeled accordingly, and were equipped with alloy components." UO8's were not made using 531 tubing!

Picture please... I havent seen any other version of the U-08 with the circle around the badge on the seat tube. Did your have one?

With some fishing around hopefully one of my 20+ LBS will have the tools to get the job done. Lots of PUGS here

It would help if you would clarify who you are addressing with your question.

Have you looked at this web site yet: https://retropeugeot.com/

Well maybe I was mistaken in identifying mine as a UO8, but after I researched it thats what I concluded. It was my first vintage so I was a bit ignorant and I admit I could have made a mistake. Here is a link to my Flickr with pics of the bike now as my campus beater. In person it clearly says "Reynolds 531 Butted" but it was hard to get a good picture of it. There is only one pic of it how it was when I got it, and its pretty poor quality.

You have a PR-10. Just the three main tubes are Reynolds 531. It's a good bike.

Well after some more research I see that mine is not a UO8, my mistake. I think I'm more along the lines of this

Mine has the 49d crank and the ridgid alu rims. Now that I've learned more it took me about 10 minutes of research to figure it out haha. Before I spent a couple hours and was still wrong.

I beat you to it.

Awesome Work folks. I will have to keep you posted on my strip and build. I did find out that only the higher end UO-8 had the plastic headbadge. The lower end models had the metal decals.

I think you got that backwards.

Nope, nothing high end about the UO8. The ones with the plastic headbadge were just made in different years than the ones with the decal. I had a 1975 UO8, with a plastic headbadge.

Building a UO8 from the frame tends to be more expensive than building up a similar Japanese bike due to the unique french sizing (parts cost more). Basic consumables: cables, tires, bearings, etc., pricing is no different.

English BB will not fit, you have a french BB, and a french sized headset and stem as well.

Hmmmm. I might have to change my mind about this frame. If I didn't have to worry about the headset and the fork it would be a different story. But I was looking for a bike that I could just swap my Japanese parts onto, and thats not going to happen with this guy
plus I'm sort of on a budget, will this end up being over $100 including a new Single Speed French BB, fork, headset, and paint? I have pretty much everything needed after that. Do you think it will be worth it?
Not to mention the extra time spent on stripping (crank and paint) and painting. Which the seller offered to provide help/materials/tools. I bet this will have a better ride than my Dept store aluminum road frame. My girlfriends Centurion Sport DLX rides like a dream, I'm hoping this frame will have better ride quality.
Thanks Again I love this site.

The UO-8 is a low end bike, but people rave about the way they ride. Buiding up that frame will probably be very expensive. I suggest that you start with a complete bike and not a French one.

Thanks I'm considering looking at other bikes!

Grand Bois is one of the Peugeot cognoscenti around here - if he'd steering you away from French bikes, disregard his sage advice at your own risk. FWIW, I agree with him - start with a non-French complete bike, or at least a complete frame set.

No good can come from you trying to make the one you have work for you. That path is fraught with peril, and is guaranteed to bite you in the ass many, many times.

I've rebuilt several French bikes - Mercier 300, Peugeot PX-10, Peugeot P8, Follis, etc. Working on the bikes isn't difficult, in and of itself. But as already noted, it can be a real challenge to find tools (or at the very least, a viable workaround), and especially challenging to find parts. One important question that bears asking - and this is because I can't see the dropouts in the photos provided - are you going to need an RD hanger? A lot of Peugeot frames have been drewed for some reason and hanging a derailleur can be interesting (to say the least) if someone has had a go with a grinder! (Take this as the words of experience!) I really love the way my Peugeot frames ride, by the way. You just need to ask yourself if it's worth the time and expense. I guarantee this $20 frame is going to cost a couple hundred bucks for fork, bars and stem (yes, those are special sizing too), French pedals, front and rear derailleurs, Mafac (or similar style) brakes, and so forth. Best wishes, and please post some photos if you decide to trick this ride out.

I don't think U0-8's had RD hangers to begin with - I'm pretty sure the rear dropouts are stamped and the RD is hung with a claw. Could be wrong, though....

Also, with a forum name like "fixedgear80", I'm going to throw a dart and guess that the OP doesn't care about RD hangers or lack thereof.
