Bonn reached the national league's finals six times, in 1997, 1999, 2001, 2008, 2009, and 2023 albeit coming up short on each occasion.

A year later, the club was relegated, and the associated economic problems eventually lead to the 1992 merger of the departments of the two basketball teams to BG Bonn 92.

But already in the 1995–96 season the team finished the second division unbeaten and moved up to Germany's prime basketball league.

There, the Baskets managed to establish themselves immediately, supported by an ecstatic home crowd at the newly built Hardtberghalle of the Hardtberg School Center.

Thus, the Telekom Baskets became Germany's first basketball club to build its own arena with adjoining training center.

The Baskets then intensified the training of their own youth players and in the 2006–07 season started a cooperation with former rival Dragons Rhöndorf.

With only 14 wins and 20 defeats, the Baskets finished the season ranked 13th and missed the play-offs for only the second time in their club history.

For the 2011–12 season Mike Koch remained head coach of the Telekom Baskets and built a new squad.

New additions such as Benas Veikalas, Tony Gaffney, Talor Battle, Daniel Hain and Andrej Mangold and most notably former player Jared Jordan joined the team.

A few months into the season the team was supplemented by forward Jamel McLean, who replaced Patrick Ewing Jr.

In May 2013, as the successor to Michael Koch, the Telekom Baskets Bonn presented Mathias Fischer as the new head coach.

Fischer had worked for the LTi Giessen 46ers before and had been responsible for several youth programs and national selections of Germany.

The Baskets finished with a 12–22 record that included a string of 14 consecutive losses in BBL and FIBA EuroCup, culminating in Fischer's dismissal.

Following the conclusion of the regular season, the management also decided to part ways with point guard Andrej Mangold who had been with Bonn for five years.

[1] Major additions for the 2016–17 season included former Bamberg player Ryan Thompson, point guard Josh Mayo, and center Julian Gamble.

In the playoffs, Bonn managed to win the first game of the quarterfinals against the defending champs Brose Bamberg, but ended up losing the series 1:3.

The following 2017/2018 season, Bonn nearly could gain home court advantage in the first round of the playoffs, but just came up short in this race despite finishing on a good fifth place with a 21–13 record.

[2] Voigt parted ways with Bonn after the 2020–21 season, Tuomas Iisalo was appointed the new head coach in May 2021.

The unexpected Champions League title had drastically increased the team's marked value which caused the players and coaches to accept higher salaries elsewhere.

On January 21, 2025, Telekom Baskets Bonn announced that Roel Moors had been placed on leave, with Marko Stankovic taking over the head coaching responsibilities.

Through building the Telekom Dome, the Baskets have further professionalized and intensified their youth work and, together with the cooperation partner Dragons Rhöndorf, offer a consistent system for young players for personal and sporting development.
