The club contested the Challenge Yves du Manoir final, losing to Section Paloise 13 to 11.

The club made it to the 1997 final of the French championship, where they went down to Toulouse, 12 to 6 at Parc des Princes in Paris.

The club saw similar results in their 1999–2000 Heineken Cup season to that of the 1997-98 competition, winning two of their six pool fixtures, not moving into the finals.

In the 2002–03 Heineken Cup the club achieved its best result yet, finishing second in their pool, winning four of their six games, but still missing out on the finals.

CSBJ, however, finished the league season in a safe spot (11th) and were able to provide LNR with sufficient financial guarantees to enable them to stay in Top 14 for 2009–10.
