I’m just spending a bit of time building the pivot back up with epoxy. I’m using Permatex Steel Weld metal-loaded epoxy. It looks pretty pro because it’s in a twin tube but, disappointingly, just smells like Araldite with bits in. Anyway, the old arm had worn a slot in the pivot and I’m...

Great story! What’s the frame? Was going to say Pennine but on a closer look the faded lettering doesn’t actually look like it says that! You should put some bar tape on it though, even if it’s budget cork tape. It’ll make the handlebars way comfier and take a surprising amount of shock out your...

100% agree @Woz about the replacement de-plenishment thing. Certain components (for a lot of bikes) you can still get cheaply and easily, while with others you’re using up a very limited stock of originals. In my case there are either no originals left or, if there are, I’m going to wear them...

That was exactly my intention and it lets me experiment with a technology I haven’t used yet!

Well, there has been an unexpected turn of events. The 3D-printing company offered me a very generous introductory offer which brings this back into play. I've been meaning to try them out for a while for some projects at work, so I've ordered one up to see what I get. Should get it in about 2...

Great find!

Noted. I won't get those then!

Loads of cool touches on that GF. I like how understated it is. What are the tyres that are on it at the moment? I’m looking for something similar to make my mtb more road-friendly.

^ Great bit of recollection! I love stories like these!

That derailleur looks fab!

I don't have a way of making it nicely myself - but you got me wondering how much it might be get a new one CNC'd or 3D printed. Quick down-and-dirty in Solidworks... CNC in Al-Cu4Mg similar to duralumin: 3D print in Al-Si10Mg: The 3D print is quite a bit more expensive than I was...

Stronglight 49D fit on modern Shimano square tapers. They have 50.4mm bcd so you can put pretty much any size chainring on them. I have 48/28 on one set and 54/46 on the other. Both have TA rings. Watch out because they come in both English and French pedal threads!

Nice one! That looks like it was WELL corroded in!

Lol, yeah I don't want to risk using it because it's paper thin. I think with a half-moon shaped shim bonded into that side it'll be nearly as good as new again.

The good news is the derailleur cleaned up nicely and under the grime it’s in really good mechanical condition: The bad news is that it’s a completely different size! Digging around the internet, it looks like there were English and French versions of these early Cyclo derailleurs. The...
