They're really cheap, makes me curious why. I've had experience with cheap ebay spokes before, they were crap, the thread stripped easily, the nipples were soft metal that was easily ruined with the spoke wrench, and just overall very flimsy feel, turned out to be way worse than 40 yo stock spokes. Not saying that these are cheap ebay spokes, but just curious if anyone had any details or info on these.

Thanks in advance!

I used these on the front wheel of my 1972 CB450. They seems sturdy and the plated finish looks great. No issues with rounding or stripping the nipples as they the wheel was trued-up.
