That's the designed built in rim wear indicator. You're not supposed to use the rim once it's appeared, all in the manual.Looks like it's scored all round too

Consider me thoroughly chastised.
Front wheel not quite there yet but keep an eye on as the rim wear indicator might just be coming through from the photos.I guess it's just that. Surprise. Four people at work have had Bromptons way longer than me - one's had his 8 years - and not one of them mentioned rim wear.
I'm also heavier (16 stone) and I ride quicker than any of them though (normal 'cruising' speed in the Brompton is about 17-18mph), so am also likely to be much harder on the brakes.
That said in those 2,200 miles the bulk of them have been done doing laps of Hyde Park. I can easily do two+ laps without touching the brakes.
I do have a very steep hill near my home end of the journey, but I only ride that in school holidays when I don't have to put my bike in the car while I drop my daughter off. Other than that, it's very flat.
Anyway, I took some better pics of the crack, the uncracked bit, plus the front wheel to try and ascertain what I'm looking out for.
Rear wheel wheel without the crack. What is it here that indicates the wheel is worn?

Front wheel - does this need replacing too?

Based on the newer photos I'd say there should be a good case for warranty replacement.I guess it's just that. Surprise. Four people at work have had Bromptons way longer than me - one's had his 8 years - and not one of them mentioned rim wear.

I like the mavic idea, the B's used to be scored in but the scoring caused work hardening, essentially making it the last part of the rim to survive. The new indicator appears like magic when worn. The OP's initial photos show a crack where the indicator is, hence the flaming they got.(Idle interest) what am I looking for to see the wear indicator in the original photos? I used to run Mavic 719 rims which had wear indicators in the form of a hole drilled part way through the rim from the inside. When it became visible from the outside it was time for a new rim. The indicator was only in one position though. Other rims I've had have a continuous groove in the brake track. When that disappears, again it's new rim time.
Well it seems like the shop believes it's just wear.
Which it probably is, but as I say, there was no 'indication' of any real wear before it went.
I guess forewarned is forearmed and all that.
The Brompton warranty covers the frame, not consumables. Way back in the dark ages I had frame welds go on my first Brompton - replaced under warranty without question.So you have to pay? I must say the Brompton warranty seems to be a bit like Teflon. I had to pay to have my chain and sprockets changed after 500 miles/5 months!
