Bertin C 37 Restoration Part 4

The previous installment of the C 37 restoration post did an overview, with links, of the four different approaches to renewing or “restoring” an older bicycle. In the case of the 1970s Bertin C 37 sold to me by Tim M. of the United States, I chose to undertake a restification (a restoration/modification). The image of the bike in its original state, as when owned byTims Bertin C 37 blk Tim, shows a good “ten foot bike”. This is a phrase stolen from the car hobby and refers to a vehicle seen from ten feet away (about 3 metres). It simply recognizes that the flaws and deficiencies cannot be easily seen and that the vehicle looks quite presentable from that distance. If you click on the image it will enlarge and look quite presentable. Click again and issues begin to manifest themselves.

There are visible scrapes on the downtube, the left fork leg chrome looks iffy, the seat stay cap decal is peeling, the red Bertin foil decal on the seat tube has gouges, none of which is surprising on a 40 year old bicycle. Tim’s presentation of the bike is attractive and appropriate for a 1970s production racing bike but, realistically, the finish is tired and in need of renewal. Since the C 37 was a stop gap while the restoration of Tim’s favoured C 34 was completed, eventually the bike was sold to me “as is” when he no longer needed it.

Once the bike you intend to rebuild is in your procession, you will need to do a pre-assessment to decide what needs to be done and how to go about doing it. That’s what I did once I had the bike out of the box Tim had shipped it in. In that case, Tim had been very clear regarding condition and there were absolutely no surprises when I assessed the Bertin.  My intention from the beginning was that this C 37 would undergo a restoration and be documented on this site. It was on this understanding that Tim sold me the bike.

So, in this case, the first step of deciding to either preserve/refurbish or to restore had already been determined in favour of restoration. The question then came down to whether it would be a full period correct restoration to factory original or if it would be a restification which would preserve the general period feel of the bike but improve functionality with improvements like upgraded chain, cluster and other visually unobtrusive changes. Ultimately, I selected restification. The bike itself was an ordinary example of a C 37, much less common than a Peugeot PX 10 or Gitane Tour de France but by no means a unique you-must-preserve-this-example of the breed. If this was Patrick Sercu’s World  Championship Bertin that would have been a whole different thing!

If this were a restoration, the black paint colour and red decals would be unchanged as would the OEM equipment (which in Tim’s build was already upgraded). From the factory this could have been the base level all French components, like Tim’s, a Shimano gruppo like 600 or Dura Ace or Campy Nuovo Record/Super Record. Frame clips would be the norm and the forks would need to be re-chromed. Since I was doing a restification, none of that was going to be true.

When I conceived of the idea to do the restoration, I already owned a C 37 from the mid-1960s which had been modified and Bertin C 37 Feb. 2013upgraded into a randonneuse by the previous owner. I had subsequently done further upgrades and had the bike re-painted in red and black, not  knowing, at that time, that they were Bertin’s racing colours.

Since I already had a light touring bike with fenders, lights and a rack, I determined that the newer, 1970s C 37 would need to be a sportier bike for faster rides. At my age faster is a very relative term! As well, it would not have fenders to make the bicycle more easily transportable and would not be re-painted in its original black and red colour scheme as shown in the top picture. That was the colour scheme on my earlier C 37 as shown on the photo to the left.

Instead, I intended to adapt the bike to my preferences within the conventions of the mid-1970s. By then, frame clips were going out and braze-ons were coming in. Good thing because I have been gouged and sliced ‘n’ diced too often to tolerate clips when I have a choice. So, no clip ons, braze-ons only for cable guides, shifter bosses, a single set of water bottle bosses and cable stops. As well, the colour would have to change to avoid duplicating my current C 37. Instead, since I am Canadian, the bike will be finished in white with red decals and accents like tape and cables.

Another driving fact behind the re-finishing decision was that the paint was not really salvageable. The frameset was rough when Tim acquired it and it had not healed! Consequently, the deterioration shown in the images below informed my decision to do a full repaint on the frameset.

As can be seen from the photographs above, there was really little choice in selecting a re-spray for this C 37. Clicking on the photos will enlarge them and they will enlarge again after clicking for a second time.

So the choices have been made, in this case, for restification and a full re-spray. The framebuilder called today to confirm braze-on locations so the next post will feature the modifications and metal work which will precede the paint and application of the period correct decals.

  1. The decals on your C 37 are the exact ones that were on my C 37. The only braze on that my frame originally had was a rear derailleur cable stop. I added some braze ons when I had it resprayed. Until I saw this C 37 I couldn’t remember if mine had a Bertin decal on the down tube. I guess that it didn’t. I just got Bertin decals but the one for the seat tube is not original like the one in your photo. BTW, there are a couple of iterations of my C 37 on your blog. I’m looking forward to your progress. Best regards.

  2. Don-
    It’s nice to hear from you again. I enjoyed doing the updates on your Bertin’s previous formats and if you use your new decals, would love to share that with readers as well.


  3. Jim-

    I think that your “restification” process is exactly the correct approach to use. One complaint though – you need to go faster. We all can’t wait to see the final product, it’s gonna be great!

  4. Hi, Tim-

    Thanks for the confidence! I will be posting briefly this weekend on the frame work done to date. The framebuilder tells me to look for the painting completion to occur by New Year’s. I am hopeful!
