If you are set on "upgrading" this bike, the first thing to do is to completely strip the frame of all of its components, including the fork and remove all of the old, dirty and/or dried up grease. When all is clean, reassemble the headset and fork with new grease. Then check the frame to make sure it is aligned properly with the proper drop-out spacing.

Once you get the frame set-up properly, you can then build it up with your new components. Personally, I would clean, re-lube and adjust all of the original components and re-use them.

If you're wanting to verify the year of the bike, you can probably find a date code on the wheels. The Rigida Chrolux rims sometimes have a date code in a diamond, like <74> for 1974, and the Normandy hubs may have a date code under "Normandy" like 11 76 for November 1976. If both wheels have the same year markings, it's a good bet that's the year of the frame.

Read through some of the "Clunker 100 Challenge" threads, lots of photographs and narrative of how people overhauled and made this type bicycle into something they enjoyed(usually) riding. Don

For what it's worth, my beater/commuter is a 1970 UO-8, red with decals like yours. I bought it as a bare frame in the early 1970s as a UCLA grad student, when I worked at a Peugeot-Nishiki dealership. Mine is a great ride, but only because it has aluminum cranks (Sugino), aluminum road quill pedals, aluminum rims (700C front, still 27" rear), SunTour ultra-6 freewheel, SunTour rear derailleur, Shimano front derailleur, SunTour ratchet barcon shift levers, aluminum bars, Salsa stem, and a Terry Liberator saddle.

John E knows his stuff.

The old Peugeots are great bikes, once you put on aluminum wheels. I got one to use as a beater bike and once I added the alu wheels it quickly became a favorite. One thing led to another, and this is the result:

I found that the Mafac brakes work extremely well. I am using Campagnolo Nuovo Record levers on my Peugeot, but Weinmann or Dia-Compe levers work very well also. The hubs are fine, as long as they are cleaned and regreased. As for the handlebar stem, pull it and check the expander slot for cracks. If there is no crack, remove the fixing bolt and drill a hole at the top of the slot. That will stop any cracks from propagating.

As for the crank, the only issue is if you need a smaller gear. They work fine as long as the gears are ok. If not, you might be able to modify the existing crank to accept a granny gear. I admit this is a little outré, but I had a machinist modify an old crank to accept Spécialités TA chainrings. The crank works very well this way! Anyway, my point is, those old Peugeots make great bikes and there is a ton of experience here on how to do it.

Here’s the modified steel crank:
