I feel your pain. That’s a tough pill to swallow, especially on the first ride. With that said, from their website, “Hayes Bicycle Group (HBG) warrants Reynolds carbon rims against manufacturing defects with a limited lifetime warranty. This limited lifetime warranty covers the Reynolds branded carbon rim if damage occurs while riding in normal and intended use.”
I’m not a lawyer but I could make a pretty good argument that a bad crash which involved sending you over the bars is not a “normal or intended use” incident resulting from a manufacturing defect. Zipp for example specifically exempts crashes from their warranty.
I remember reading before I bought my Reynolds that their warranty changed recently. I don’t recall the specifics, but that was early this year. That youtube video is from two years ago.
It is poor form to not respond though, I’d be interested in hearing what sort of run around you’re getting as well because while I own Reynolds wheels, I haven’t had to interact with them yet.
