His high degree of Thoroughbred blood brought an elegance to his progeny, and this trend toward a lighter dressage horse has been on the rise since he stood at stud.
He consistently produced offspring with good shoulders and toplines, as well as elastic and rhythmic gaits.
Breeders continue to cross the B-Line with the G- and D- lines to produce successful dressage horses, as well as those by Argus.
Bolero has also made a name for himself as a sire of broodmares, producing 317 mares that went on to be registered, 96 of whom earned the status of State Premium.
Three of his descendants medaled at the 2004 Summer Olympics in Athens, Greece: Brentina, Bonaparte, and Beauvalais.
