I think my AD is the Team model, same frame as the Superleicht but a different color and sold as frame and fork only -- at least that's as close as I've been able to recreate from the sparse online materials. Mine has parallel 74 degree angles, with full butted 531. I guess that's crit geometry? I've built it up with a triple and high handlebars anyway. It's a somewhat light bike (~22 pounds) and a lot of fun to ride.
