Am I guilty of 'clickbait?' I don't think so, but could be 'guilty' as I have a hunch........ Is it a locating tab, and part of the seat-post sleeve?
The attached is a photo using a cheap endoscope I bought recently, so maybe of interest to others here. I intend to start poking it into the chainstays ot my other bikes, just to see what it reveals.
The Brompton is a 2007 superlight, which wasn't used, and was kept indoors until a couple of years ago when it became mine. I keep the spare inner tube inside a ripstop nylon sleeve within the main frame tube, so I was concerned about rust. It all looks good through the endoscope, and using a torch the bare metal looks good. Instead of using waxoyl or similar, I decided to paint inside the main tube, using some grey primer thinned with white spirit - I poured about 20ml inside and shook it/ moved it in all directions and left it to dry with any excess dripping out onto a 'catch cloth'. That should stop any rust, but if it does occur I'll be able to see it against the grey (my reason for not using red oxide primer)
