I got a mixte from the local thrift for 25$. It has Rigida 27 inch alloy rims with Peugeot/Malliard helicomatic six speed freewheel. The fron't derailleur was a Huret. I think it is the rear Eco derailleur based upon a japanese web site I looked at. It had Stronglight cranks with a plastic pop on chainring guard. The cranks are surprisingly light. The pedals are Lyotard with the metal dustcap cover. They still spin nice. Any idea what the bolt circle diameter might be on these? I was surprised to see non cottered cranks. So I think this is a later model. The bottom bracket cable guide is a screw on plastic type not braze on.

Is this a hodge podge of french parts on a newer frame? tubing is carbolite 103...but the other tubes seem thinner.

First, We need pictures, nice, big clear ones.

Second, is it lugged or lugless?

If you have a ruler, all will be revealed. Here:

Early 80's P8 variant. The component mix is correct for the time period. Simply based on a mixte frame and 27" alloys its easy to ID.

1. Whats the decal scheme? Rainbow? Stripes? Checkerboard?
2. What color is it?

Earlier Stronglight cranks have a proprietary 122mm BCD, whereas later models typically followed the modern 130mm standard. I concur with miamijim that you probably have an early 1980s model. The Helicomatic hub was a short-lived evolutionary dead end which helped bridge the transition from freewheels to freehubs. Likewise, I don't think Peugeot used the Carbolite 103 nomenclature for too many years, and the company changed from externally lugged to lugless frame construction in the early 1980s. Thus, it should not be hard to pin down your model year +/- a year or two, given that Peugeot's decals changed every few years, as well.

The higher end (Reynolds) Peugeots still used lugs into the eighties rainbow paint schemed bikes. I'm not sure if Carbolite bikes were ever lugged? Can anyone say otherwise? I haven't found a bad riding Peugeot in all of the bikes I've ridden though. Most of them are decent IMHO.,,,,BD

That's a real interesting question. Prior to introduction of Carbolite 103, there was Peugeot 103 tubing that was used on lugged frames. When Peugeot introduced the lugless P8 and PH10 in 1982, they used Carbolite 103. Lugged models were spec'd with Peugeot 103, with one exception. The lugged PBN10 got Carbolite.

All this begs the question, is Peugeot 103 the same as Carbolite 103? Did Peugeot distinguish between the two just for purposes of marketing their new lugless technology? And did the PBN10 really use Carbolite 103 or was it a catalog error?

I cant answer all of the qestions but:

1. Reynolds 501 tubing was on both lugged and internaly brazed (lugless) frames
2. Reynolds 531 was only used on lugged frmes
3. "Peugeot 103 special" was used on both
4. Peugeot "Carbolite 103" was used on both.

Peugeots nomencature was odd. The subtley changed the parenthesis:

"Peugeot 103" lightweight tubing to...
Peugeot "Carbolite 103"

In the early 80's it doesnt seem clear as to why which models had what tubing. If I had to guess I'd say its the same tubing based on them calling the 103 'lightweight'.

P9/some kids bikes lugged "carbolite 103"
P8/P18 internally brazed "carbolite 103"
PH18 internally brazed "Peugeot 103"
UO10/UO9 lugged "Peugeot 103"

To the OP...27" alloys and stronglight cranks were not OEM. Pics please.

Oh? That's weird about the 501 being used on both external and internal lugs. I thought all 501's were lugged, as mine is. Thanks for the info! Something else Peugeot to keep an eye out for, hehe.

My Peugeot collection has jumped a couple of notches lately, with the addition of two Reynolds models. Both lugged......,,,,BD
