I have this and like it. You need to loosen the stem bolts and turn the bars down. I have integrated cables with two piece bar/stem (BMC ICS). I’d like to see it work with a 1-piece bar/stem.
Closing it correctly can be fussy and TSA doesn’t always take the time to line things up perfectly, But my biggest critique is that the tires have to be deflated to fit in the built in locations. If you run tubeless it might make a mess. But I’ve thrown wheels in there with wheel bags and was able to close the case. And TSA managed it too. Whew,
