Brompton’s don’t hold up well, especially the rear triangle, here is my 2007 that I’m restoring at the moment.

Was that stored for decades in a pond?

Do not mention it on a Brompton reddit!! You will get downvoted so badly!!:gun: :laugh:

Rust simply does not happen to those guys. I guess perhaps they do not take it out into the rain and do things like kick their missus out to sleep in the garage so their Brommie can take her side of the bed!! Seriously they are precious about the brand.

And do not even try to explain that you cannot take the bike into your office at work with you. :banghead: They simply do not understand that concept and the poor dears have a breakdown at that!! 🤯 :laugh:

Sorry I have jusst learnt a bit about emojis, I am tryhing them out more!!

My GF understands that the bike comes into her flat with me and is stored next to a warm radiator.

No, just left in a garden uncovered

It turned out well though, after a lot of work and far too much expenditure. I wouldn’t do another one this bad.

Bromptom rust - in my experience - has been worst in the main frame tube; from the front hinge forward (photo). Water must get through there & then it's slightly downhill to the headtube.
Bilt Hamber Dynax - JB was recommended for an alternative frame saver - works well.

The rear triangle lacks any caps/ plugs. The top & bb sections are an open invitation for water ingress on a rainy day.
I'm trying a set of earplugs in place for the top section (photo). Plan to cut/ plug some old wine bottle corks for the bb side.
