1980 Peugeot 12 vitesses

I have an early 80's Peugeot which I have upgraded but now would consider a new Shimano Crank triple set. Does anyone know if there is a crank available for this bike, how much work this is or if it is indeed possible to perform?

If not I'll be looking at a new Fuji Newest.

The bike is Model # PBN 10S 56

If you add a triple you'll have 18 vitesses.

It shouldn't be a problem at all since a 1980 Peugeot won't have French threads. You'll need a bottom bracket the correct length for your crank and possibly a front derailer.

Beware, a peugeot of that period may very well have a Swiss threaded BB!

I have a 1981 PSV10; which has a Swiss threaded BB. Swiss threading is sized 35x1 like French but the drive(right) side is reverse threaded like an English BB.

Thank you all...in the meantime, I have passed on the triple crank and went to a bike shop to review options for this bike without going too nuts.

I dismantled the crank and the lower bracket. The crank is in top condition...Stronglight 40/52. This went well but the drive side was Left threaded and very difficult to move but I got it eventually. Bought a TIOCA sealed BB cup set...B-301 versus adding a new sealed bearing unit. All my parts were near new condition...no wear showing. I installed the drive side cup but could not use the adjustable cup as it would not thread easily even with force..yes the threads were clean. The bracket is all set.

I bought a set of Shimano Pedals PDM 515 and a pair of NIKE shoes for the pedaling upgrade. Here I had difficulty installing the pedals...very tight again. The Peugeot crank arms show 20- 9/16 . I may have to have the hole tapped again since the pedals do not seat all the way. I'm not comfortable with the pedals being in half way. I did check the out going pedal threads with a caliper, they measured .550, the new ones were .560 Not sure why the threading should not accomodate the new pedals easily. I thought threading for pedals were common. Anyone else have similar tightness issues???

I upgraded the bike a few years ago to add some speeds.... it has a Tiagra 9 Speed rear derailleur, a Mavic MA3 rim with a Shimano 105 hub, as well as a Shimano HG-50 Hyper glide cassette. This initial upgrade made a huge difference in performance.

Thanks for the feedback. Hope to have my pedal issues resolved soon. Should be an even better performing bike for this last $150 upgrade.

My 1981 Peugeot PSV10 has Swiss BB, English derailleur hanger, 9/16 Pedal threads. The seatpost, headset, stem and handlebar are French.

About two years ago I upgraded? the wheelset, cassette(9 speed), pedals(look) and chain(9 speed) It shifted(friction) and functioned well.

I have since restored it to it's original 12 speed design as it came with a helicomatic freewheel, tubular tires and Mavic wheelset. But I have many other bicycles to ride. . .

My 1980 PKN-10 has a Swiss-threaded BB. It also came with 20x9/16 (ISO) pedal threads in the Stronglight cranks.

I've dealt with a number of Pugs with Swiss threading from this period. It is a very likely possibility. This may account for your problems in threading in the new BB. The difference between Swiss and English isn't much, and I have had folks tell me they have fit English cups into swiss frames. In my experience, they (English cups) won't thread in (to Swiss frames), though you can usually get the cups a turn or two.

I have a number of Pugs from the 79/80 time period, and the Stronglight cranks on them were all English threading for pedals. Generally, Stronglight would mark threading on the cranks, either right where the pedal went in or on the back of the crank. 14x1.25 equals French threading, 9/16 means English. So yours would be English.

I have had an English-threaded fixed cup in my Peugeot for several years. Yes, one can indeed "fit English cups into Swiss frames," if one interprets "fit" to mean "force." Eventually, I'll probably disassemble it to learn whether the cup rethreaded the frame or vice-versa, but for now I don't dare remove the fixed cup when I repack the bottom bracket.

I have a metallic green AO8/UO8 (RECORD DU MONDE) that looks like your bike, exact same stickers, with large flange Sunshine hubs and the Frank Lloyd Wright Styled Step Cut-outs in the lugs. Front fork is chromed, now pitted.

The serial stamped on the dropout on mine are staggered, it says: "11 9 03 20", I have no idea, how to read this for a date.
On the bottom of the BB lug is stamped "RY F4"

The bike has the MAFAC RACER centerpull brakes, Sugino 171mm Cranks with 52/40 teeth, Suntour GT Derailleur and a metal seat post. The stem on mine had been upgraded to an SR Forged, but not by me, however the handlebar is not a drop but an easy rider.

This bike has options like white cable piping, narrow painted fenders(white) and a rear mounted generator for a headlight and taillight as well as a chomed rear rack.

This was given to me around 20 years ago and left it to rot in the rain, under a tree as I had left my hometown to work abroad. Now, tha I have returned, I am in the process of cleaning it up, there is some rust here and there and could be used as a beater, but it just looks too cool and for a steel framed bike, it is unseemingly light in weight and yet smooth for the ride.

I will post a picture as soon as I can withn a few days

hello
i have a peugeot and i think its an '87 mont blanc but i am not sure 100%. i am posting some pics of the bike. can anyone please help me with some infos about the model and year,the saddle,back and front derailleurs (model,manufacturer etc), brakes etc? i am also curious about the decals: can they be found somewhere for sale? i have to mention that this is not bike's original colour ( i understood it used to be mauve but im not sure of it) so if anyone can help me with the exact colour it would be great ( im thinking to paint it back to original colour). the rims are not straight so i would like to know if i can find some to buy and where from. thank you so much

Holy thread resurrection. And welcome to BF. You've obey'd the first rule - pics req'd. I reposted one of the complete bike for you.



And that's a different color scheme. Can't say I've seen one like it before.

And a link to some catalogs - LINK

Decals that you might find to work - LINK

thank you very much. next time i will try to be more careful. thanks for the tips and for the help. the colour scheme is different allright. the previous owner didn't know much about bikes.i am still trying to find the right colour (as in paint) for the bike. the decals are pretty ok. i just have one question: what would you choose if u were me: the 85 decals or the 86 PH10 ones?

Since entirely period correct decalling does not seem to matter to much to you with your bike, I suggest that you go with earlier style decals (80 to 83...anything Pre 84 is better) that did not have the rainbow diagonal color slashes on the top and seat tubes. For some reason Peugeot decided that their traditional checkerboard and lion graphic designs were not cool anymore by 1984. Us Peugeot fans almost fainted when we saw the 84 bikes with these color slashes when they came out. Later designs into the 90's weren't that much better either. I've since learned to unconciously cancel out the color slashes in my mind, everytime I look at my 84 PSV.
