[2] The 1975–76 season Brina ranked 12th in the domestic league and was downgraded to Serie A2 Basket,[3] although in Europe managed to play at the top 16 group phase of the 1975–76 FIBA Korać Cup.

In the 1978–79 FIBA Korać Cup qualified automatically to top 16 and ranked first with a record of 5-1 wins in a very competitive group against Inter Slovnaft (2nd, 3-3), Cibona (3rd, 3-3) and Orthez (4th, 1-5).

In the final (March 26, Country Hall du Sart Tilman, Liège), Arrigoni Rieti was found to opposite one more Yugoslav club, the emerging Cibona of Andro Knego, Aleksandar Petrović and Mihovil Nakić, and won the title.
