Chim 500 wheel question

[The_Ox]

Hi all,

I wonder if anybody can help me. I noticed yesterday that one of the wheel hub cap, bolt cover things on my Chimaera 500 (standard 500 wheels) has come off somewhere. I have no idea how this happened but, the long and short of it is that I need a new one. Does anybody have any ideas about where I might get one from?

Cheers,

Ox
