The name Roulers (French for Roeselare) and the drum brakes make me think this is in fact a Belgian bicycle. The picture quality isn't great, but if that dark spot on the left fork blade is in fact a braze-on for a tax plate, that would confirm it.
A very nice 1950s Cazenave, restored well. I'm trying to ignore what looks like a trapped cable under the bottom bracket, as for a first restoration it's lovely. Owners translation below.
Hello everyone,
I've been looking for a few weeks for a vintage bike from the 50's with a green colour. An advert on the lbc caught my eye, attracted by its green colour, I made an appointment, deal done.
The bike is almost complete, but missing, saddle, grips, front light, pump, rear light cap and pedals. Nothing serious. It is in its original condition, tyres cooked of course, never restored, very dirty and very greasy.
I was just surprised that the luggage rack was blue and not green.
I set about dismantling it, then elbow grease for hours and hours with cleaning products, degreasing and greasing the bearings.
I changed the consumables and installed the missing parts.
The paint was really well protected by the varnish. The Cazenave is now satin, I hesitate to varnish it. Some varnish left under the bottom bracket.
It was my first restoration, a beginner's impatience meant I didn't take any photos before and during the restoration.
Mea culpa
Fortunately, I've still got a few bikes to restore, and the progress of the work is also part of the fun.
Mid 1950s Magnat Debon, as found. Owners translation below.
Here's a bike you don't see very often because it's not produced very often. Magnat Debon, best known for his motorbikes.
Magnat Debon as well as his cousin, Monet Goyon, have for Parents, Terrot. (As best as I can translate I assume parent company? GIGFY)
These bikes are exact copies of Terrot.
Later, when Peugeot bought Terrot, in 1959, only Terrot was left to continue, to be produced.
Magnat Debon was produced in Dijon, just like Terrot.
It is especially the brakes rather unusual for this type of bicycle, which made me buy it.
Yes, the front brake studs have just been re-brazed, because they were un brazed (Assume broken GIGFY) It's an old repair.
Originally, the bike is all assembled with SIMPLEX, it's fitted with Huret from 1978.
A deviation for the rare and wonderful, predates Pinion by a considerable margin. Magnat Debon was innovative. With an early patent for a gearbox in the bottom bracket.
The engraving on the Magnat Debon disc to change gear on the 3 speed is P = petite M = moyenne G = grande. Sadly this one has a missing cluster and the one remaining is damaged. Somewhat picture heavy, there is a manufacturers cut away so you can see what should be inside. Owners translation below
Here's my find of the year, unearthed during a visit to a second-hand shop 6 km from home. For the record, I went there to find a wicker basket for my wife. I also came back with a basket.
This bike is a Magnat and Debon Model F 2 gears in the bottom bracket, the forerunner of the Pinion gearbox.
It's not easy to date it at the moment. The first Magnat & Debon patent dates from 1902 and was for a 3-speed gearbox. The 3-speed bike was the Model G.
It seems that this model was in the catalogue until the 17s. That's a wide range, which will be refined over time.
The big drawback is that the top sprockets are missing. And don't kid yourself, finding the original ones is mission impossible. But maybe with a bit of luck, as I live in the town where the bike was designed, I'll have a glimmer of hope... But I'm going to have a look and have them made again. I found the plans for the 3-speed gearbox in the INPI archives. The 2-speed gearbox must not be very different.
