How do you veteran wheel builders feel about no-name Chinese carbon rims
building them in a wheelset for another person or a customer? Would you do it if they provided the rims? What steps could you take to protect yourself liability-wise? Thank you.

For example if a deep-V carbon rim is oval, (confirmed by 2 diameter measurements) I'll either explain that radial true may be impossible, or require uneven
tension, or in some cases refuse to build entirely.
So far my experience has been that there's more variation rim to rim of the same brand with carbon than with aluminum, but that may simply reflect the large number of newer to the business rim makers.
In any case, I generally make clear that I won't stand behind any rim failure on a rim that I didn't recommend and/or sell. If a buyer wants protection from something like a spoke hole crack or pull through, he has to buy the rim through me.

I've always made all "brought to me" rim decisions on a case by case basis. Sometimes I can know by brand experience that I'll want more dough to build a rim, or have the client accept a disclaimer. Sometimes I'll simply say no dice at any price, disclaimer or not.
For example if a deep-V carbon rim is oval, (confirmed by 2 diameter measurements) I'll either explain that radial true may be impossible, or require uneven
tension, or in some cases refuse to build entirely.

So for me the disclaimer is to protect me from having to offer goodwill repairs on stuff that wasn't my fault, by saying up front that I won't. I've never had issues about claims, but I protect myself from unreasonable expectations by saying up front that X is about as good as could be expected.

It's to establish an understanding. If I feel I need a disclaimer for legal reasons, meaning I thing the item is somehow dangerous, than I protect myself by not touching it in the first place. You cannot use a disclaimer to excuse you from your responsibility, you can only use it to clarify where responsibility lies, but if sued, it'll be the judge who determines that, not the paper.
So for me the disclaimer is to protect me from having to offer goodwill repairs on stuff that wasn't my fault, by saying up front that I won't. I've never had issues about claims, but I protect myself from unreasonable expectations by saying up front that X is about as good as could be expected.

incazzare.
I only build wheels for friends, but even so, no, I would not build rims like that. I also don't build old rims, new or NOS only.

i've never built wheels for profit. but i can say that having recently built a set of no-name chinese carbon tubulars, that they were the easiest build i've ever done.
and i recently hit a pot-hole harder than i've hit one in five years, that would be about 40,000 miles of riding. i was certain that i had ruined the front wheel or at least loosened some spokes. not the case, and because it was a tubular tire, i didn't even get a pinch flat (Vittoria Corsa Evo, 24 Sapim Laser spokes with aluminum nipples). i really couldn't believe it!
the braking is atrocious. though, they stop as well as my alloy rims, they grab like all git out. i'll be experimenting with brake pads for a while...

Where did you get these carbon rims you just built?

Just a thought for those concerned about liability issues: I'm a consultant in my "day job" and I need (often by contract) to carry "errors and omissions" insurance. It's not terribly expensive, as insurance goes. Wouldn't something similar (or even the same type of policy) be a practical solution for those in the trade?

the chinese can churn out a quality product if you order it. i have no gripes w/ what comes out of china. i have gripes w/ outsourcing to them.
aside from that, carbon clincher wheels are pointless.

I personally have built a number of "china carbon" rims, everything from fat bike rims to road rims. Since most of my communication is through email where I have it in writing, I just make sure the customer very clear that I will build the rim to the manufacturers recommended specs and if there is a rim failure I am not at all responsible and that while building, if I have any doubt about the safety of the rim I can refuse to continue at any time. I doubt that alone would hold up in court but at least I have some record of me telling them do use them at their own risk.
In reality though, these rims often are coming out of the same factories/molds as "name brand" rims we all know and trust and I have never had a single issue with one I have built. With the exception of the fat bike rims, they were all very high quality rims that built great. The fat bike rims were tolerable but there were a lot of smaller complaints I had that I did not have with skinnier options, mostly related to spoke hole drilling and variation in spoke bed thickness.

Other than that, no failures or other issues. 5 riders did the RAAM on them this past summer.
Awaiting the first batch of fat bike rims to build now for their house brand bikes. I"ll see how that goes.
