Langster, Track, Fillmore, Plug, Pompino, T1, Pista, Flyer, have missed loads I'm sure, although there are some ok bikes in that lot.
It looks like one of the above bikes after a clerkenwell/soho owner has it for six months and I think the lack of branded parts will apeal to a lot of courier/commuters who already rap everything in tape to disguise their frames identity.
Condor get parts made with their logo's on them so I don't see the problem with swobo having parts made with theirs. I'm sure its just formula china/taiwain factory parts rebranded.
That said £300 quid buys a FUJI though and the rest of those bikes (bar maybe the Pomp which is a bit better than the rest IMHO for commuting) are overpriced compared to it.
