1947 Camille Daudon – Component Details

After many years of stops and starts, I’m finally completing my restoration of the 1947 Camille Daudon that came into my possession about 5 years ago.  The above photo shows its condition when I first acquired it.  The frame had been re-chromed, but the rest of the bike hadn’t been overhauled.  There was seemingly not that much to do, but one thing that hadn’t been set up by the previous owner was the Cyclo derailleur, which uses a one-piece cable set up that can be challenging to master.  There were a few other mishaps that made the process longer than I imagined – but that is kind of the norm when it comes to restoring bicycles from this era.

I’ve previously written a great deal about this wonderful bicycle, but haven’t yet described its components, so I’ve included a compendium below.  The bike as pictured weighs about 20 lbs, and as you will see, all components were selected for their quality and light weight.

Wheelset – Pelissier Plume hubs on unbranded 650b alloy rims with Huret drilled winguts

Bars – Unbranded alloy city style bars, with wood dowels.

Stem – Camille Daudon lugged stem with hidden tool kit.  The stem clamps directly to the steerer tube.

Brake calipers – LAM Super Dural Model H with original pads.  The interchangeable hardware allows for reversing the direction of the cable (for mounting on a mixte-style frame).  The caliper arms have no up-down adjustment, meaning that brake bridge and fork length precision was required.

Brake levers – Unbranded alloy levers 

Headset – Stronglight – model unknown

Cankset – Stronglight 49 with Rosa 42 tooth ring, 165 mm arms, anodized blue.

Bottom Bracket – Unbranded alloy with hollow axle and reverse thread left side threading, weight 197 grams.

Derailleur/shifter – Cyclo Standard, Daudon modified shifter

Freewheel – 4 speed J. Moyne – 14-24 (identification thanks to reader Bruno)

Grips – Original Velox grips replaced with Felt Grenoble

Saddle & Seatpost – Ideale Model 65 with duralumin frame and alloy clamps (broken).  (The broken clamps spurred an unsuccessful years long search for a replacement, and I ended up modifying some clamps designed for tubular rails).  Unbranded alloy stem with closed top.

Pedals – Unbranded with alloy cages

Camille Daudon was known for modifying existing components and creating his own. It is possible that many of the unbranded pieces were created by him.  These Daudon-created parts might include the seatpost, bottom bracket, brake levers and maybe even the pedals and rims.

The final step is setting up the Cyclo derailleur and shifter – a daunting task.  Fortunately I recently discovered a technical guide dating from the 1930′s on the disrailigears website, which has proved very helpful.  Stay tuned for the results of the last step in restoring this wonderful machine!

1962 Cycle Competition Cyclotourisme by Daniel Rebour

I purchased this 1962 Daniel Rebour Cycle booklet from Jan Heine about 5 years ago.  Back then I carried it with me whenever I took public transportation to work (TriMet) so I could peruse its French language pages and stare longingly upon its Daniel Rebour drawings at my leisure. While I have never taken a French language class, I studied Spanish extensively in my youth and was at one time fluent in that language.  That made it easier to have a rudimentary comprehension of what I was engrossed in while bumping along toward downtown Portland on the bus. Eventually I realized that I didn’t want the pages of this rare vintage publication to become dog-eared, so I set the booklet aside in my special bin for special stuff not to be messed with.

Unusual through the frame cable routing for rear centerpull Mafac brakes.

I have consulted this little tome a few times since then when I needed some background information on components and bicycles produced in the early 1960’s.  Recently, I dug it out because I had remembered an odd through the frame cable routing for a rear centerpull (Mafac) brake.  And even more recently, I wondered if this little booklet contained any information about French Cyclo rear derailleurs.  I figured probably not, as these derailleurs were becoming obsolete by the late 50’s.  And, I was right about that.  But, I once again was drawn into this publication, which is organized by bicycle component categories:  Frames and tubing (Le Cadre); Bottom Brackets (Les Roulements); Cranksets (Le Pédalier); Chainrings (Les Plateaux); Pedals and Toe Clips (Pédales et Cale-Pieds); Wheelsets (Les Roues); Tubular Tires (Les Boyaux); Derailleurs (Les Derailleurs); Brakes (Les Friens); and the remaining chapters on saddles, handlebars, and accessories.

Daniel Rebour’s treasured drawings are featured in a number of print publications.  One of these is Frank Berto’s The Dancing Chain.  I frequently consult Berto’s book for insight and guidance on setting up vintage derailleurs.

Daniel Rebour contributed significantly to our understanding of vintage bicycle components.  He left a legacy that all cyclists benefit from, especially those of us committed to preserving the legacy of vintage bicycles, and we are all the better for it. I am grateful for his contribution.

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.

A British Cyclo 3 speed model

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.

 

Shifter cable routed through derailleur spring.

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.

Rigida 650b wheelset with 1941 rear hub – a flip flop version with butted spokes.

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!
