Ritchey and Deda both have bars with aero tops that are compatible with the bar end junction. The Ritchey is more compact, IIRC the Deda bar has a tad more (5mm?) of reach and just slightly more drop. Also you have to be careful shopping for that Deda bar as I believe there was an older version that looked like it but didn’t have all the holes or maybe the bar end didn’t fit, I’m not sure.
