So those modified Mafac brakes... Actually there are two types of modifications to be carried out on these brakes for them to perform properly on this build. The first category of modifications is actually a mere natural upgrade using the improvements made on the build quality of some parts...

It would be actually quite interesting to have pictures of frames from the early 60s with brazed-on features. That could trigger an interest on those "innovative" frames - and frame builders from that era 😉

Hi there, I don't remember for sure but, as the frame, when I picked it, had the name of a local club sponsor - Giai, I guess it was a vynil transfer. In addition, if you look carefully at one of the very few picture I have of the frame as it was originally, you will notice that on the seat tube...

Like this one... More to come 😏

Absolutely! If I wasn't currently in pain with a sore back I would post a picture from behind the front mech cage showing this later nearly touching the cable. It actually took me a lot of time to finely adjust the front mech to achieve this balance enabling to shift properly without touching...

And now, the last piece of the build - the brake calipers. As the Gravster will be fitted with a pair of Campagnolo Athena ergo levers the most obvious and logical option for the brakes would have been a pair of side pull dual pivot calipers. However the clearance available with such brakes...

Great looking frame 😊 And the gruppo is a perfect match! My "personal" one - pun intended, is still at an unfinished stage... unlike the bookshelves behind - the big boss kept an eye on the completion of that latest.

And this is how the finalized drivetrain looks like...

And now the last part of the drivetrain - the chain. Although I keep and store previously used chains like any other part I've used previously, the odd thing about these used chain I have in stock is that I systematically refuse to fit them on any new build... Especially if I have high...

Now the penultimate component of the drivetrain - the front derailleur. My first choice was to fit a Huret front mech. Yes - that's a bit strange, a Huret derailleur on a Peugeot... That's usually regarded as sacrilegious since both marques seemed to ignore each other for most of their...

Eventually I removed the external teeth lock washer as its width was both "a tat too wide and... shrinking" 😂 Yes - that's a strange concept, a shrinking wide width... But that's actually what happens when using an external teeth lock washer... The teeth will flatten as the bolt is tightened...

You're probably right... But as I had to send the frame back again - once the hanger had been brazed, for the dropouts to be aligned, my imagination started to wander a bit and I wondered whether I should not check the hanger as well as I experienced some rear mech adjustment "issues"...

Below the thick lock washer with its external/diagonal teeth

For the time being that's exactly what I am going to do... The overall wheel "looks" centered... I have made a series of measurements at the brake bridge level with my vernier and it seems that the rim is off-centered by 1mm. As most of the intended usage for this bike will be slow speed gravel...

Thanks for this. Actually it took me a few minutes to figure out why... But yes it makes perfect sense. Initially my first instinct was to assume that 1mm washer on the DS would induce 1mm off-center and re-dish... That's the target... I was not really happy with the initial...

That was my first intention until Guinessisgoodforyou raised the point of redishing... And that makes a lot of sense. Especially since the current washer is a relatively thicker than first thought external teeth lock washer - closer to 2mm-thick rather than 1mm...😬 I would honestly prefer to...

I think that should be the easiest way... I will check that.

Indeed - and I would certainly benefit from this as I have more than a dozen pair of rims and an equal numbers of hubs of all era and spoke count to assemble... From large flange FB hubs - for a late 50s PLX10, to more recent Campy Shamal/Electron hubs for my late 90s Bianchi Mercatone... I...

That's a great idea indeed. Thanks 👍 The only thing is... I've never actually worked on wheels 😬 A bit ashamed I confess... Plus I don't have a jig... But as one of the contributors put it recently on one of the best vintage bike topics I've read so far - that is "Early 50s La Gazelle -...

So, next item in the Gravel's drivetrain assembly... the cassette. Might seems odd at first to dwell on a set of cogs as it's quite straightforward - especially when it's related to a modern cassette, on a modern hub. Indeed from a gear range and technical assembly there is no issue. No need...
