@ PeterXu

The customer has business with you, not with the factory. If you set your business quality to be dependent on the factory, then you cannot control this and will be bad for your business.

You have $100 bigger margins than your cheaper competition. I suggest from this buy some frames to have for spare parts or when customer needs replacement. Also there are not that many things to check on a frame to see if it is good quality - you should check every frame and not send any that has flaws. You should know the product you sell well and you should know what to check on it. If you send a frame with short bolts it was your responsibility, not the factory.

If you only relay the problem to the factory, you are only a middleman, you have no extra costs (other than communication) from such customer service and ultimately you are not financially motivated to send good product.

I believe you provide the best communication experience, you probably get the better frames from the factory, but you only provide the same customer service as the factory when something goes wrong. For people in US, Europe, etc. such service is not enough and they are willing to pay more to have a better one.

@Peter are all frames sold in a grade and b grades? Is the only difference between the two the quality of carbon fiber that was used? I, and I'm sure lots of other forum members, would be interested in this info.

I have purchased an IP-057 frame with Bert, after I sent the money already do 12 days and they did not respond more emails, also sent to Peter and he also does not answer, I'm thinking I lost my money.
