That riser bar is a 3D printed bar, according to Trace Velo. It could be a preliminary version of the HBR20. It doesn't look like a lot of flare. The HBR20 also doesn't have a huge flare. Only 6 degree. Going from a 380 to 410 in the drops. If it is a preliminary version they sure did change the stem a lot. I like the shape of both handlebars. I ordered my frame with a HBR20. Just to get rid of the 30mm of spacer underneath my HBR17 on the LCR18-D
