1982 Peugeot PH12E Centenary Model

I was recently very kindly given a Peugeot frame – a PH12E Centenary model with some of the original parts still fitted. Unlike a lot of the similar survivors on the internet, this example has been used and obviously had an active life. Paintwork is tired and transfers are rubbed. The question arises, is it worth restoring? My answer is a resounding “Yes”, firstly because the bike rather than been put away, “because it is a centenary model and might be worth something”, was actually ridden as intended. It has a history of use and shows signs of that use. Secondly, Peugeot embraced the 'aerodynamic' culture of the time and fitted some now rare parts to the bike. The great French rider Bernard Hinault, 5 times winner of the Tour de France had ridden a specially built Reynolds tubed aerodynamic Gitane time trial bike in the late 1970s. Cycling Weekly (UK) coverage of the time featured riders in skinsuits riding time trials which was to lead to the development of low profile time trial bikes with smaller front wheels. These would see use in the professional peloton time trials, until banned by the UCI. Greg Lemond pioneered the use of Tri-bars to obtain a more rider aerodynamic position in the professional peloton. Shimano produced it's 'aero' AX600 and AX Dura Ace between 1981 and 1984 according to the Velobase website.

The frame I was given was missing the wheels, Simplex SLJ6600 rear mech and the top mounted down tube levers. The orginal parts fitted would obviously stay, but could I find the correct replacement parts? The most serious challenge would be the Simplex rear mech. I believe the SLJ6600 was introduced in 1982 and was the first mech to to have an angled parallogram like Suntour and Shimano. The original rear mech was branded 'aérodynamic'. Apart from the scarcity of the mechs, the other factor would be price and condition. According to to Disraeli Gears page entry for the Simplex SLJ6600, the springs lost tension very quickly rendering the mech less than effective. This probably explains why the original rear mech was missing. A search on French ebay over several weeks identified a few examples for sale. Some were the later 'SPIDEL' branded version and other examples looked to be in poor condition from the seller's photographs, but not reflected in their asking price. I eventually located what appeared to be a good example and managed to secure it by auction including delivery for a fraction of some of the asking prices on ebay in the UK. Probably one of the biggest hurdles in terms of sourcing original parts had been overcome. I was also gifted boxes of parts along with the Peugeot frame. During the sorting process, I came across a set of Maeda Suntour top mounting down tube levers carefully bagged up. A quick check proved these were off the Peugeot, so another major headache in terms of original parts, was thankfully overcome.

The Peugeot PH12 model was usually made from steel Carbolite tubing, the frame having the appearance of being lugless, but in fact the lugs are internal. Whilst a carbolite tubed frame is not as light as one built with Reynolds or Columbus tubing, fitted with a decent set of wheels, these Peugeot bikes ride very well indeed. Probably a lot to do with the French frame geometry. The 1982 Carbolite tubed Centenary PH12E has an 'aero' seat tube and down tube. The gear cables are routed internally through the down tube from the top mounted friction levers. The other significant thing is, the down tube friction levers and chainset are Japanese, not French. The chainset is an alloy SR Custom model with detachable alloy chainrings, a change from the usual Stronglight alloy crank with swaged steel chainrings.

The 'aero' style seat tube means the seatpin, from necessity, is very short. The top of the seat tube is round to accept the seatpin, but as the seat tube quickly changes profile, the seatpin has to be much shorter than would be found on a bicycle with a full round seat tube. Again, Peugeot use a much smaller diameter seatpin than found on other bicycles. The original seat post is a plain model, necked in at the top, the original saddle being retained by a steel seat clamp bolt arrangement. In amongst, the various store of parts within the Springhill Cycle Collection, there was an alloy one piece seatpin with an integral seat clamp. It has been in the store for a number of years and although not original to the Peugeot it will be used on the bike as a nice finishing touch. It is an unusual and certainly period correct part. The upshot of all this is, the 57cm frame will not suit a tall rider because of the short seatpin. 

It is my intention to restore the bike as close as I can using period correct parts. I still have to source the correct Mavic rims and a small flange Q/R rear hub with a 1982 date code to complete the wheels.  The fact some parts are missing may have more to do with their lack of durability/suitability as the bike was heavily used. I will probably fit a pre-owned Concor saddle and replace the Lyotard flat steel touring pedals that have been fitted in lieu of the 'aero' type pedals that were original to the bike. Although the Shimano PD-1050 105 are 5 years later than the bike, they will make a reasonable substitute. They are in keeping with the 'aero' theme and could represent a likely modification during the bike's working life. The Springhill Cycle Collection is happy to restore the bike in an as used condition. It means the collection now holds a 1982 Peugeot Centenary model along with a similar, used, 1987 Raleigh Centenary edition bike.

Frame numbering

One of the most frequent postings on web forums by people who are starting to collect bikes is 'can anyone identify my bike or frame?'  The easiest route to possible identification is find the frame number.   It sounds simple enough, but it is made a lot easier if you know where to look.   Volume bicycle manufacturers like Raleigh tended to use the seat lug, as in this 1925 Raleigh roadster.

The size and font of the numbering could also change over time as illustrated in the Raleigh Moulton frame number, although the location of the frame number was the same.  

 

One caveat about Raleigh frame number information on the web. Sheldon Brown is quite accurate on Raleigh frame numbering, except where he supposes about Irish Raleigh production. His information is simply incorrect. As it was posted 'on the internet', it is assumed by many, as an incontrovertible truth, when it is not. Sheldon's pages were a work in progress. Unfortunately, this all came to a halt, on his untimely passing. I will blog accurate information on Dublin Raleigh frame numbers using known examples at a future date.  Raleigh have also used the back of the seat tube, either below the seat lug, or above the bottom bracket, the underside of the bottom bracket shell and rear dropout as location of frame number.  Some of these locations were used for 'badge engineered' Raleigh production.  As mentioned above, the style of font used in the sequential frame number changed over time and the example below was found on a 1920s British roadster.  

Other British bicycle manufacturers used either the seat lug or a rear dropout. BSA sports frames tended to have the frame number on the left rear dropout. 

Hercules in the 1950s also used the left rear dropout and used a different font to BSA. 

 

Sunbeam during it's time of ownership by AMC used the right hand rear dropout on some models. 

Bespoke custom frame builders in Britain used various locations to install a frame number. Unusually, some builders put their frame numbers on the bottom bracket shell at the down tube lug. 

Others stamped the underside of the fork crown. It was not unknown to have the frame number on both the frame and fork. 

Often the frame number was stamped on the fork steerer tube as well. 

However, easily the most common location for a frame number was the underside of the bottom bracket shell. 

The number was usually stamped in line with the axle, or at right angles to the crank axle and parallel to one on the bottom bracket cups.  Imported Peugeot bikes from the late 1970s/early 1980s had a frame number stamped into the bottom bracket shell which was parallel to one of the bottom bracket cups. Peugeot also had a paper identifier covered in clear vinyl wich identifies the model, frame size and sequential frame number. 

The location varied between the underside of the bottom bracket, bottom of the seat tube above the bottom bracket shell, or on the left hand chainstay.

The model numbers appear to be slightly different according to the country of sale. Gitane put their frame number on the left rear dropout of their tandems. The sequential frame number is on the bottom part of the dropout and the year identifier above. 

 

A further complication and a bit of a red herring can be a re-finisher's number. 

Frames were often stamped by a re-finisher before being enamelled to make sure the right frame and fork were returned. These are usually 3 digit numbers and can confuse as they are on both frame and fork.

Once you have located the frame number, the process of trying to indentify  the machine that you have found can begin. Finding the frame number can be difficult if it is only lightly stamped, or been damaged on a rear droput, or covered up with paint. Some small bespoke frame builders didn't bother with a frame number. Late 1980s volume manufacturer (Londonderry built) Viking 531 frames also don't appear to have been given frame numbers. I have also found 1990s examples of Dawes 531 frames with the same problem. Finally, another recent phenomenon which can add to the confusion is post code stamping of a bike frame to try to deter theft and ensure the frame is returnable to it's owner. These are usually 7 digits, usually two letters, three numbers and two letters. They tend to be stamped where they can be easily found, so keep looking to see if there are any others!
