Sup’s Friends 1985 Peugeot P8 Build

[Suprachrgd82]

Thus begins my journey down the road bike path. I know nothing about road bikes and the componentry so it’s gonna be long journey. This bike belongs to a good friend who wants to begin cycling. Being that my garage is full it only makes sense to build something that won’t take more space.

The plan is to end up with something reliable and slightly more modern. Maybe 700C, integrated shifter/brake levers, 2x8-ish, Shimano 105 class drivetrain and red.

Please help me if you are a roadie.

The frame has just been stripped and some measurements recorded.

Hello @Suprachrgd82. This side of the code is not that different to the others, I think you will not find things as strange as you think

First up seat posts for those Pugs are quite unusual size wise so don't chuck that one out. If you want a more modern clamp people sell new 'uns but at a price.

After a good clean maybe consider either coating the rust as is with rust treatment (Krust, hydrate 80) or rubbing down to metal and covering with something (clear nail polish perhaps).

If you want to move en masse to newer components it may be more economical to get a donor bike and swap bits over. Something like this for about £50 has everthing you need for a transplant to brifters. If that is out of budget or the spirit of this excercise then maybe junk that idea and get some brake pads, chain, freewheel, cable, bar tape and tyres and just clean up / refresh what you have.

24 mm seat post, Stronglight do a micro adjust post. Quite rare though.

Welcome to the other side (I'm imagining this in the voice of King Willie from Predator 2).

The good news if you're going to modernise it a bit is that there are some cable stops on the down-tube, so you can use more modern shifters without any adaptations (although without barrel adjusters, but you can do without those, really).

When it come to brakes, you will need 'nutted' brakes, which most modern brake are not (they use the recessed-nut type). Tektro make some, which should also have enough drop to make sure the brake pads reach the rims. Either that, or it is possible to use the recessed-nut type with some adaptations - depends how much work/money you want to put into it.

I knew roadies were a bit odd, but that bar position is just *depraved*

Nothing helpful to add, except to say I hope you enjoy the build and your friend appreciates your efforts.

Still getting measurements, and am poking at the front end.

The stem has a 22mm diameter. Will this frame/steerer accept a 1” threaded headset?

Only if it's french threaded 25 x 1 inch

I would suggest this bike is not really suitable for fitting modern Shimano 105 parts. This bike is a low end sports bike and there is nothing wrong with that, it's just not within the category of a "lightweight" bike which would at a minimum have a frame made from butted chromoly tubing, eg Reynolds 501.

I would clean up the bike, remove rust, regrease bearings, replace any unusable parts and ride the bike as it is.

French stems are 22mm. Normal standard stem is 22.2mm. French headset, bottom bracket, freewheel, pedal threads are different. You could have a mixture of the above on one frame. I've got a Peugeot which has.

I think if spaced at the rear 126mm. You could fit seven speed 105 I have. Picture is circa 1994 this one long gone.
