An advantage of owning a Brompton TitaniumOn the subject of rear triangles, I'm told the bridge on which the brake calliper is mounted can be prone to rust. Worth keeping it clean and lubing it occasionally.
You are right though, on my stock Brompton I have had to touchup/paint this part where some paint flaked off.
These people are a great source for Brompton parts
Brompton rear sprockets and spacers - Brilliant Bikes
They stock pretty much every part and provide fast free delivery. I have used them a lot. Its not hard to maintain a Brompton. The sprocket is simple to remove, plenty of how-to vids on line.
