Looks like improvements all round - Did you order it from the UK or US ... or direct from far east ?
I feel Brompton have got a bum deal - just as folding bikes start to take off (and they were a major influence in this), their patent runs out - and lower cost copies (OK with improvements) come out. I guess they must now trade on their brand - ie do we want want a real 'Gucci' or a far east 'Gucci' copy.
