I have been looking on Ebay for the same thing. If any body has some info I'm also very interested! Mostly build quality, hub quality and well just quality in general
i did a little unscientific research on ebay regarding carbon wheels from China. seller 2011cycling2011. I went into there history and pulled seller reviews from their feedback. I then sent ebay messages to 5 buyers of the wheels. Got 4 responses; 1] great wheelset 2] not as pretty as zipps but ride fine 3] light cheap and really fast shipping. got mine in Texas in 6 days 4] Got mine in a weeks time, really nice wheels/ Smooth and comfortable to ride all day. couldn't be happier and set a new TT personal best on a course i had done many times. I would certainly buy them again.
So, not sure what company the wheels you are talking about are from but try to find a few buyers in the sellers history and see what the users have to say.
I have heard that a few of these companies use the old molds from Zipp and Reynolds but of course i have no idea what truth there is to that and i certainly do not believe it just because someone said it. : )
Let us all know if you go for them and how it turns out.
I've purchased carbon clinchers from FarSports (dealt with them directly) & have been very happy with them (Basalt brake track, 60mm, etc). I've been considering another set with discs, if only to justify acquiring (n+1) a disc cross-bike. Desire however exceeds paycheck, so that's on hold for a while....
There is a whole board of folks who dabble in the open mold frame/direct from factory carbon experience - and the Moderator of the board (Killerbee) posted this reply to a question a day or two ago on eBay carbon wheel sets.
Good luck !
Checking out 2011cycling2011 tubulars and they all have brake tracks. FarSports has them without but a lot more expensive. This would be my first foray into carbon and tubulars. Any concerns about removing the glue and effecting the epoxy? Could that be a factor in cheaper layups?
