This is a synthesis of a few threads I have seen on road.cc in the last year. I read that the New Starley bike and PlanetX are actually using standard Chinese frames and wheels that are imported and branded and obviously marked up in price. I don't know if this is true but a poster here said it is widely know. I posted on a thread about new Zipp wheels retailing at about £1700 and said I had seen similar PlanetX wheels for £400 which I fancied; someone replied saying that you would 'feel' the difference between the two. Finally there was a long running thread about someone's 'Chinarello' that they had built from clone parts from a website discussing the bike's performance and cost.
So what I am asking is this; obviously Chinese parts aren't just made out of balsa wood and these British brands are sticking their names on them, but are they a reasonable investment? Are they 80/90% the quality of some big name US/Italian labels at half the price (which would be worth it) or do the prices genuinely reflect the difference in quality? Should I just buy what I can afford now and have a dream Italian bike in my mind for the future or wait?
