As you can see from the photo below, the time has come to adjust the chain tensioner on Brahma. Having only on full-size bikes, I'd wager that it is a bit tricky working on the Brompton. It is quite compact (which is its asset) and so it is hard for me to get my fingers in tight corners and adjust the tensioner. It could also be that I do not have the right repair stand, but that takes a lot of money to replace and not an option, at least not yet.
I went to Home Depot today to look for some, but they didn't have any that I liked. Yes, they had some big kits, which I do not really need. I need to look online, I suppose.......
Do you ever work on your Brompton? Perhaps on the chain tensioner??
