Yes, that should be chrome plated, like mentioned here.
I’m really sorry to say that the French Strida guys seem to be a bit strange:
-At the shop is no “effet miroir” Strida available…
(If they announce a chrome one, they should be prepeared that anybody WANTS one)
-Ordering a freewheel for 29 € would cost additional 32,50 € shipping…
(Hej, we’re both in Europe, that’s not overseas 
)
-Running an internet shop means you should be able to speak English…
(Hope the French nation will recognize sometimes that English speaking is needed to understand the whole World, it’s NOT a prostration for the Queen)
Maybe we should post it at a Brompton forum?
