Project88

Hello there I posted a threaten the commuting forum regarding replacementparts for my bike. The said YouTube in this forum are the guys to ask. OK I have a 1988 Peugeot 6 gears in back shimanno shifters. And derailurs that I don't know the model of the shifters do say SIS light action . My question is when its time to change the drivetrain what options do I have foe parts ? Idk if it is French speced or not I just know its Canadian made. Will I have to hunt down French spec parts or can I use anything ? I ask because its French and the seat tube is a nightmare to find a longer one because it uses the 24m and not the standard 25 or 27. So I want to know will other parts be as hard and expensive to find

A picture would help a lot in determining what you have and what can be done with it. That said... "SIS Light Action" is Shimano, so the bike is likely not French sizing. Any parts from Shimano made up to about mid-1990s should work.

Hmm, seems unlikely that a Canadian-made Peugeot of that era have a 24mm seat post, but I could be mistaken. It probably doesn't have French threads, but a photo or at least a model name would be helpful to confirm that. Either way, it shouldn't be too much trouble to update an '88 Pug...

edit - beat to the punch. What bluesdaddy said.

Will this bike should take mostly modern or readily availbe ISO parts. Peuget stopped using French sizing around 83-84 and this bike read likes lit is slightly newer than that.

if you need a longer seatpost than the standard length, then the frame is probably too small for you to start. Ebay is your one stop spot for used components, lots of good stuff.

To the best of my knowledge the Canadian licensee of Peugeot never used any French-threaded parts. For teh seatpost, you likely have one of the models that featured a sleeve in it. If you remove teh sleeve, you will find it much easier to find a longer replacement seatpost.

I have an '80s Canadian Peugeot at my parents' house in Pennsylvania. It was all standard stuff except, as you noted, the 23.8 mm seatpost (15/16"!).

The color scheme was black with rainbow, but there were some differences that allow me to distinguish between French and Canadian Peugeots. It doesn't have the fading checker board graphics that the Frenchies have, and it has a Maple Leaf on the drive-side chainstay.

I believe the model name on mine was "Marseilles" or something like that.

Frankly, I didn't ever care for the ride quality, but that could be related to the moustache bar setup that I put on it.

i have the same bike as yours black nd all with maple chinstay gaurd

so i can use any standard comps? can i change the gears out back for something with 7or higher rather than 6 ?
I have never riden a high quality bike actually this one was my first "real" bike but i dont feel it bad I really cant complain about it. it also takes a load pretty well without affecting the steering for commuting she does well

I think it maybe a size too small but I didn't know it at the time but also the post is really small I never. Measured it but it is by far the smallest post I have ever. Seen I really listened maybe another half inch and it will be perfect.

Yes, probably, but if the seat tube is 24 mm, DO NOT LOOSE IT. At least, not if you can't match up the frame without the sleeve in place. Buying another one could become a significant challenge.

You can use any deraillers and any downtube or bar end shifters in FRICTION mode but unless you get vintage SIS shifters from same era you will lose the indexing feature with replacement shifters, if you stick with your original deraillers. You can change out the deraillers and shifters with new ones that are modern 9 or 10 speed but to get them to work in indexed mode you would almost certainly have to change your rear wheel hub to a modern one using a 9 or 10 speed cassette. The most reasonable solution is to replace parts only when they need it. If you need a new freewheel in back you can get a replacement one. If you need a new derailler you can get a replacemnet one new or old just forget about the indexing feature of your old shifters. If you need new shifters just get replacement ones and use them in friction mode and forget about the indexing featuer of your old shifters. If your 6 speed freewheel in back doenst give you an adequate range of gears then you can get a wider range freewheel (you can use a 7 speed) but you will likely need to get a longer derailler.

FWIW I have an '89 Peugeot Versailles which is more or less original. The seatpost is about 23.8mm. There is no sleeve in the seattube; the seat tube is necked down at the top to this diameter.

@ the OP, is there a reason you need to replace anything in the drivetrain? You should be able to maintain & use what you have, unless there is something damaged or that you're otherwise dissatisified with.
