Bromptons Flip for most of their New Price , if you Hold out long enough.
the Factory has Racks of the various component parts in the various colors .
It is possible to get frame sub assemblies, if you were in England and deal with one of their Big dealers Like SJS Cycles
but I Wont say it is something easily Done or Cheap, Planet Wide .
may be better to Just get over it and ride the Bike As it Is
