I'd send the wheel back to I9 and have them fix it. Every time I've dealt with them they've been awesome. If it's a manufacturing issue with the rim hopefully it's limited to a bad batch or something and they'll replace it with a rim from a later PO.no that spoke is basically pristine, and there are 2 or 3 others that are pulling also. had the same thing happen to this wheel 2 years ago so idk, thought it was a fluke then, but not sure now.
a) have i9 rebuild it again
b) buy another hoop from someone else and reuse the hub
c) buy a whole new wheelset and sell these as is to someone who probably wants just the hubs.
the thing is iv been really happy with these wheels otherwise.
