Vintage 70's Peugeot... cotterless bottom bracket?

Hey guys, I was wondering if any of your French bike experts could identify this bottom bracket. I am about to get this bike off craigslist. Owner says it's from the mid-1970's, but AFAIK they had French-threaded bottom brackets. But from the picture:


It seems like it may be a square tapered BB. I don't see any cotters. Anyway, I was planning on fixing this bike up and knowing what BB it had would help a bunch!

Check out other pics of the bike:

The BB is definitely a replacement, the cups require a spline-tool for removal.

But with lugs like that, you have to buy the bike. Like, do you have any choice in the matter?

Hope the bike is really cheap, as it needs quite a bit of work and it is a basic, gas pipe U08.

I like those Aztec lugs... my 1955 PLX8 has them.

The bike has had the cottered spindle replaced with a square taper...those thread are still gonna be French and I can't see the bearing cups in that picture.

Velo Orange now sells French threaded cartridge bb's in a wide range of widths which is great.

UO8's are not made of gas pipe and are actually very nice riding bicycles with great road geometry... their tank like nature stems from all th steel parts that are attached and swapping those out for lighter parts turns an okay bike in quite a nice one.

That frame looks pretty well used so one would not want to pay very much for it.

OK, high ten steel versus gas pipe.

Oh yeah the bike is gonna be free. I realize how much work it's gonna need (and I don't even know if I can do it all myself!), but after a spiffy paint job I feel like it would make for a basic commuter bike.

I'd just clean up the frame and do some minor touch ups to address any serious rust issues and then ride it as is... the theft factor should be pretty low.

I'd like to see how the BB comes out. Those are Shimano crank bolts. It is possible to thread in British threaded BB"s but its to be a cartridge that normaly threads in from the right with an loose cup that also threads in from the right.

Some folks reamed and retapped French BBs to Italian.

I picked up the frame this afternoon! I took off all the components except for the BB. Just to clarify, I need this tool right? http://www.coloradocyclist.com/product/item/PARSJBBT22

Anyway, I'm stripping the paint with a chemical stripper and we'll see how it goes from there.

It was a pain to take off the seatpost and stem! Were tolerances really tight or did its old age just wear on it?

Maybe, assuming it's either a Shimano or Sugino sealed cartridge. You should try to count the number splines (20) just to be sure. I have that tool, and it worked on a Sugino BB, but the thing that concerns me is that the right side threaded ring had a flange on it, which I don't see in the photo. I also have a French threaded Phil Wood BB in an old Gitane frame, which has threaded rings without a flange and only 18 splines, in which case you would need a Phil Wood tool.

Cool Peugeot! I am finishing up a 1980 "gas pipe" Peugeot grand sport right now. My frame was in similiar condition to yours, as was the price! Mine doesn't have the interesting design in the lugs yours has but it does have a sweet headbadge and most all the components are Peugeot branded. The bike was rough and I'll probably have more in it then I should, but I like the bike for whatever reason and am excited to know that I brought something from the brink back to life. I'm waiting for performancebike to get me the rest of the pieces Monday, tires, handlebar wrap, brake levers, etc.

BTW, there's a guy on eBay selling old peugeot decals, I bought a set and put on after the repaint, they look good, and were less then $20 shipped.

My gas pipe PA10 on tubulars weighs less than my Reynolds 531 PX10 on clichers. It rides better, too. I'm convinced that wheel weight is what really matters.

i like the look, jasonb! i hope mine turns out as nice. i started stripping the paint using chemical stripper and, boy, is that hard work! I'm a little worries that the braze-ons aren't in good shape. i may just take them off the frame, make it smooth, and turn it into a single speed or a fixie with a front brake only. what spacing do you have for your rear wheel? getting decals is a pretty good idea. i may have to look into that when i'm closer to completion.

The rear wheels is 120mm. I bought them on eBay for $125 shipped with cog, lockring, and freewheel. Not exactly Deep V's, but I was trying to keep the build under 250, since I didn't want to sink much more into the bike since it probably wouldn't be worth it. I knocked off the braze-ons (except the top cable guides) and smoothed them, definitely cleaner. The simplex shifters, wheels, cassette, etc were junk, so going fixed/single speed was by far the cheaper/better option. I don't know if I'd paint it black again, it came out great but was a LOT more work. Try and leave some original paint on if you can, so the new paint will have something to "bite" to. Areas of my bike that I sanded to bare metal were harder to paint.

Or a derisive 'gas-pipe-ing' forum.
