Setting Up a French Cyclo Rear Derailleur, Part II

Cyclo rear derailleur with cable installed – 1941 Goeland

The 1941 Goeland I have been gradually “restoring” (translate: preserving and making rideable again) was equipped with a French Cyclo rear derailleur.  The French model is not to be confused with its British counterpart.  Although the two derailleurs operate with a helical sliding bolt and friction shifting, the set-up of the cables and shifters is different between the two country’s versions.  The French model features a c’est la vie attitude:  no cable stops; no housing; set up success determined by your close connection to someone in the know.  The British version has cable stops at both ends and cable housing for the entire length of the one piece cable (often described as a two piece system) which has a nipple welded to the middle of the cable to fit the slot in the helical bolt.  The two Cyclo models seem to be a case of British pragmatism vs. French ingenuity.  I think both are to be enjoyed and experienced.

According to Classic Lightweights, the Cyclo rear derailleur was first introduced in France in 1924.  It was the most widely used rear derailleur from the 1930’s through the early 50’s.  Disrealigears has a more extensive discussion of the company’s history which you can read about here It seems that while the British version of this derailleur thrived in the 1920’s through the 1950’s, the French version was under attack by and ultimately succumbed to Simplex.  That may explain the difficulty involved in setting up the French version of this rear gear changer.

Once you have sourced an appropriate cable (I harvested a NOS cable from a British Cyclo, which had its nipple welded on to the cable – you can also source a nipple that can be threaded on to any tandem length shifter cable), one of the most baffling elements of the set up is how to keep cable tension on the rear nipple, which must engage the helicoid bolt in order for the gear to shift.  The photo above from a 1956 advertisement shows that the cable is routed through the derailleur spring. This definitely helps keep the cable nipple in place, but it is not a perfect solution.  Nevertheless, this is how I set up the shifter cable for the 1941 Goeland.

The 1940s Cyclo shifter is a pretty little thing, weighing about nothing, but looking very nice.  The arm of the shifter angles away from the frame just enough, but the length of this shifter’s lever is short compared to others of this era. The entire device is made from aluminum alloy, except for the outer steel cover, shown above. 

This is the “conjoiner” which connects the two shifter cable ends together.  It is probably actually some kind of evil spirit.  No joy can be derived from working with this little device.  It fits into the slot on the inside of the shifter.  I can’t really comment from here except to say:  watch out!

Here is the conjoiner coming out of its slot  (of course!) on the shifter.  I had become too confident when I thought I had my cable tension dialed in. So, when the conjoiner popped out of the shifter, I realized that where was no way to avoid the double wrapping and shifter twisting steps that I used when setting up a 1947 version on my Camille Daudon.

I am still in the process of restoring the 1941 Rigida Deco 650b wheelset.  That has involved re-tensioning the spokes, cleaning and reviving the rims, and rebuilding the hubs.  The freewheel has now been removed, cleaned and lubricated.  The threads on the filp flop rear hub are in good shape, so once I have the freewheel back on the rear wheel, with a period correct chain installed, the set up of the rear derailleur should proceed with haste – or so I hope!

JOS Vintage Head and Tail Lamps

The 1941 Goeland that I have been restoring – a process involving bringing it back to its original condition as much as possible – had a JOS head and tail lamps that were incomplete.  The head lamp was missing its internal parts, with only the pretty aluminum shell remaining, while the rear lamp had still had its “guts”, but was missing the reflectors.  I was fortunate to find a replacement set recently on eBay.

And, I still have some money in my bank account!  This replacement set probably dates to the late 40’s or early 50’s.  I decided to harvest the “guts” of the replacement head lamp and put it into the original shell, which still has some of its red highlighting visible on the JOS starburst logo, as you can make out below:

It was very easy to remove the lens and electrical internals and transfer them to the original shell:

JOS lamps are sought after by restorers and collectors, but I haven’t found much information about the company.

The replacement tail lamp was not an exact match.  However, the length is about right, so I will remove the old “guts” of the rear lamp, and probably not even need to drill any new holes in the fenders.

The JOS replacement lamp has some interesting markings:  Agre’e’ T.P. C 89.

The reflector is cracked, but the rest of the lamp appears fine.

I look forward to getting these replacement lamps installed and functioning, using the Radios Z 27 dynamo that is original to this Goeland, shown above.  Setting up dynamo wiring can test one’s OCD levels and related need for counseling.  Below and above is a nice and professional looking wiring job, from the original bike.

I’ll try to follow this example when I rewire the system. After that, a little mental health therapy may be in order!

1941 Goeland: Disappointments and a Decision

Louis Moire founded Goeland Cycles at 44 Rue Etienne Marcel in Paris in 1935.  He intended to offer high quality frames which could be built up around lower cost components.  He called himself a “constructeur”.  In reality, Goeland frames were probably outsourced to other builders.

A few years ago I purchased a Goeland bicycle on eBay.  I knew from the photos that the bicycle needed some minor frame repairs, but judging from the seller’s photos, nothing seemed catastrophic.

The seat stay rack attachment had failed, and the mixte sloping top tube attachment to the right side seat tube had also cracked.  Another brazing mishap involved the rear rack – one of the brazes had failed.

But, after preparing the frame to be cleaned and waxed, I saw that the Cyclo derailleur mount on the drive side chain stay had also failed.  I hadn’t noticed this before, but if you look closely at the above photo of the right side derailleur mount braze to the chain stay, you can see that it has detached.

That made me think about this bike’s history.  While theorizing is probably something to be avoided, I do believe that this frame was built in 1941 (at least the Durifort main tubes which are beautifully brazed with nicely filed Oscar Egg lugs).  The frame and fork feature numerous “41” markings.  However, some of the components indicate that this bike was built up for riding in the late 1940’s.  The brake levers and calipers are MAFAC, a marque not introduced until 1946 or 1947 according to my research.

The wheelset for this bike dates to 1940 or 1941.  Since all the other marks on the frame are “41”, I have  concluded that this bike is a 1941 frame.

I have theorized that this Goeland’s Durifort main tubes were brazed in 1941, and as you can see from the above map of occupied France this bike may have not been built up during the occupation.  Perhaps the bike was never assembled until after Paris was liberated in 1944.  At that juncture, manufacturing and other activities that had been halted during the occupation would have been put on overdrive, due to pent up demand.

As was typical in cycling workshops of the time, experienced builders would assemble the main tubes, and apprentices would be assigned the job of the “simple” brazing – rack mounts, and other braze-ons.  Perhaps this particular apprentice needed a bit more training.  If the final assembly of this bike occurred after Paris was liberated, that would help to explain the MAFAC brakes (A new marque, previously known as Securite).  However, the numerous frame failures on this Goeland are notable.  And, I think they do relate the sketchy history that accompanies the Nazi occupation of France during the mid 1940’s.  One possibility is that since metals were in low supply during the occupation, the less important brazes got minimal silver or brass for their brazes.  The bike has no dents or bent tubes, and is not out of alignment, indicating that the failures were not the result of a crash.

Annie Laurin, original owner of this Goeland.

My goal now is to honor Annie Laurin’s bicycle.  I have decided NOT to repair the frame, but rather to preserve this Goeland in its original state, serving as a map to this Goeland’s history.  That history includes brazing errors, which possibly contain some important information.
