While the rim was less than a year old so waiting to see if they will cover it or give any kind of discount on a replacement. It was sold as a 650b DH rim, but interestingly enough this same 35mm rim has been relabeled as an AM rim on their site, I think the width of the hookless edge might be too narrow / weak for DH. The 26in 38mm DH rim I rode off my DJ bike the next day held up fine so maybe i'll replace it with one of those. The thing that sucks about carbon is any kind of little crack turns into the thing ripping apart in a short amount of time. This pic was right after it happened but in the video I posted you can see it got way worse quick, and that was after hiking out and riding a smooth dirt road down really slow.
