I'm building my first set of wheels, they're all laced up, gonna move onto tensioning and truing, etc... I noticed the seam on one of the rims isn't smooth. It's a 700c sun m14A and the ends don't meet flush. I can't remember if it was like this before I started building but the spokes aren't tight or anything yet so I don't see how it could have been pulled out of whack.
it's very slight. You can kind of see it but I didn't take any pics because I didn't think it would show up well enough, you can definitely feel it, one side is slightly higher and out to one side than the other. We're talking maybe 1/4 of a mm, perhaps 1/3 at worst.
Is this something I need to be concerned with? Would this be considered a defective rim or is it just unfortunate but still usable?
