Judging from Cor Vos' photo's, I'd say a steel gazelle with somewhat oversized tubing (trapezi?). The team posed for the team photo that year with a Titan model, but clearly Van Petegem did not favor that frame for the classics. Although his bike for the AGR did have a significant down tube like the Titan, the stays are obviously slimmer than the Titan's. http://www.corvospro.com/display_results.aspx?INIT=1&PAGE=1&PERIOD=&SRC=petegem%201999
