The Broggi brothers retired during this period, replaced on the court by Lino Cappelletti (the first Cantù player to make the Italian national team) Lietti, Ronchetti and Quarta, whilst the squad was sponsored by the Milenka distillery.

[4] The arrival of Tony Vlastelica allowed Cantù, now playing in a covered Parini arena, to finish fourth in 1957–58 and start challenging Minganti Bologna and Simmenthal Milano.

Though Ignis and Simmenthal had a hold on the Italian league during that period, a Birra Forst-sponsored squad composed of Marzorati, Recalcati, Antonio Farina, Ciccio Della Fiori and Renzo Tombolato captured three successive FIBA Korać Cups in 1973, 1974 and 1975, beating respectively Maes Pils, Partizan from Belgrade and FC Barcelona.

The 1974–75 season ended with the club earning their second scudetto with players such as Marzorati, Della Fiori, Recalcati, Farina, Tombolato, Bob Lienhard, Franco Meneghel and Mario Beretta, who later in that same year would add the FIBA Intercontinental Cup, beating Real Madrid and the final runners-up Amazonas Franca on the way.

[2][3] The form from these seasons would continue into the 1980s, thanks to a squad coached by Valerio Bianchini with Americans Tom Boswell and Bruce Flowers, future Serie A all-time top scorer Antonello Riva, Renzo Bariviera, Denis Innocentin, Giorgio Cattini, Fausto Bargna and Marzorati.

Again pitted against Maccabi Tel Aviv in the final, Squibb Cantù brought 1,200 fans to Cologne on 25 May 1982, winning 86–80 thanks to 23 points from Kupec, 21 from Flowers, and 18 apiece for Marzorati and Riva.

The rest of the 1980s saw the club stay competitive but failing to add any titles despite counting American players like Dan Gay, Richard Anderson, Lorenzo Charles, Jeff Turner and Kent Benson, stalling in the league playoffs and losing the 1989 Korać Cup to Vlade Divac's Partizan.

[2][3] Riva had left for Milano in 1988 but Pace Mannion joined the club and was decisive in the conquest of the 1991 Korać Cup, scoring eight consecutive three-pointers to down Real Madrid, with Marzorati ending his career with another title.

Clear Cantù ended the season in the semi-final losing to another Italian club after being surrounded by "Saša" Đorđević's Philips Milano (who subsequently won the trophy).

The 1993–94 season saw the club playing in FIBA European League against European clubs like Efes Pilsen, Panathinaikos, 7up Joventut, Buckler Beer Bologna, Cibona or Pau-Orthez (ranked 8th and last in the group B with 2–12 record) and changing coaches and foreign players but this could not prevent the team from downgrading to the second division, ending a forty-year tenure in the first division, the Allievi family conceded the ownership to Franco Polti in its wake.

He would do better the next season, leading an American-centric group of Jerry McCullough, Bootsy Thornton, Sam Hines, Shaun Stonerook, Todd Lindeman and Ryan Hoover to a fourth place in the league, enough to qualify for the EuroLeague (though Corrado decided to renounce participating for financial reasons).

Mapooro Cantù beat Siena to win the Supercup, then triumphed in the qualifying rounds (organised at "home" in the PalaDesio) to reach the EuroLeague regular season.

[1] Though they beat Real Madrid and Fenerbahçe Ülker they exited at the group stage after losing to the Turks in Istanbul, where Manuchar Markoishvili went mid-season by transferring to Galatasaray.

The now Lenovo-sponsored team came back from a shaky start to crack the league playoffs, where – thanks to the arrival of Joe Ragland – they reached the semi-finals, losing the seven-game series against Acea Roma in the last game.

Domestically, they reached the playoffs again, with help from NBA All-Star Metta World Peace who joined the club in March, but were undone in the last game of the quarter-final series against Reyer Venezia.

In November 2015, the club was bought by Ukrainian-Russian billionaire Dmitry Gerasimenko: in the first weeks of its ownership he announced he planned to build a new arena, brought in coach Sergey Bazarevich and four new players.
