They should (and will likely) send you a new rim. That is not good but hongfu is a legit company that seems to take care of people. It just sucks because it is CNY and nothing happens for two weeks. I had a set of Farsports 24mm tubulars that arrived with the UD delam'd in very small areas at couple of the spoke holes - likely a result of drilling/tensioning.
If I may make a suggestion here is what I did: I got farsports to agree to build me a new wheel, disassembled the wheel and shipped them just the spokes and hub in a small envelope. Much cheaper than paying to ship a whole wheel to china w/ tracking.
Problem is, I only bought the rims from them. I have a custom build done on the hubs/spokes. So, that was done/paid for, now I have a rim that is starting to delaminate after just spending money on this build.
If they want the rim back, they are going to foot the bill. I sent them photos as they requested, but crickets now.
I spent money on the build/hubs/spokes, now it will have to be torn down and rebuilt with another rim.
Downside of dealing with these Chinese companies.
